The pith

Polymer stresses remain singular in bubble pinch-off but diverge far more weakly than in drop pinch-off.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper examines bubble pinch-off in viscoelastic polymer solutions and contrasts it with the well-studied case of drop pinch-off. Experiments show that threads fail to appear in dilute solutions and only form at high polymer concentrations where the process becomes sensitive to needle diameter. Simulations and analytic modeling with the Oldroyd-B constitutive relation reproduce these observations and establish that polymer stresses still diverge, yet the singularity is much milder than the one that stabilizes threads in drops.

Core claim

Using the Oldroyd-B model the authors demonstrate that polymer stresses are singular at the pinch point during bubble detachment, but the divergence is substantially weaker than the corresponding divergence that occurs during drop pinch-off. This reduced singularity explains why viscoelastic threads are absent for dilute polymer solutions and appear only when polymer concentration is raised to levels where the dynamics also depend strongly on the needle size from which the bubble detaches.

What carries the argument

The Oldroyd-B constitutive model applied to the dilute regime, which predicts a weaker stress singularity for bubble pinch-off than for drop pinch-off.

If this is right

  • Bubbles in dilute polymer solutions complete pinch-off without forming a persistent thread.
  • Threads appear only at high polymer concentrations where pinch-off dynamics depend on needle diameter.
  • Numerical simulations based on the Oldroyd-B model reproduce the dilute-regime behavior seen in experiments.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

  • The weaker singularity may produce different scaling exponents for the minimum neck radius in bubble breakup compared with drop breakup.
  • Processes that rely on controlled bubble detachment, such as foam generation or microfluidic gas injection, may exhibit reduced sensitivity to dilute polymer additives than analogous liquid-drop processes.
  • Incorporating finite extensibility into the model could locate the concentration threshold at which the stronger thread-stabilizing singularity reappears.

Load-bearing premise

The Oldroyd-B model and the dilute-regime assumptions continue to hold across the experimental range of polymer concentrations and needle sizes without shear thinning or finite-extensibility corrections becoming important.

What would settle it

Direct measurement of the polymer stress divergence rate near the pinch point that either matches the weaker Oldroyd-B scaling for bubbles or shows the stronger scaling characteristic of drops.

read the original abstract

The pinch-off of bubbles in viscoelastic liquids is a fundamental process that has received little attention compared to viscoelastic drop pinch-off. While these processes exhibit qualitative similarities, the dynamics of the pinch-off process are significantly different. When a drop of a dilute polymer solution pinches off, a thread is known to develop that prevents breakup due the diverging polymer stresses. Conversely, our experiments reveal that this thread is absent for bubble pinch-off in dilute polymer solutions. We show that a thread becomes apparent only for high polymer concentrations, where the pinch-off dynamics become very sensitive to the size of the needle from which the bubble detaches. The experiments are complemented by numerical simulations and analytical modeling using the Oldroyd-B model, which capture the dilute regime. The model shows that polymer stresses are still singular during bubble pinch-off, but the divergence is much weaker as compared to drop pinch-off. This explains why, in contrast to droplets, viscoelastic bubble-threads do not appear for dilute suspensions but require large polymer concentrations

Referee Report

2 major / 2 minor

Summary. The paper examines bubble pinch-off in viscoelastic liquids through experiments on polymer solutions, Oldroyd-B numerical simulations, and analytical modeling. It claims that, unlike drop pinch-off where threads form due to diverging polymer stresses, bubbles in dilute solutions show no threads; threads appear only at high concentrations where pinch-off becomes sensitive to needle size. The Oldroyd-B model is shown to produce singular but much weaker polymer stress divergence than in drops, explaining the dilute-regime observations.

Significance. If the central claim holds, the work clarifies key differences in how elasticity affects bubble versus drop pinch-off, with the weaker stress singularity in Oldroyd-B providing a mechanistic account for the absence of threads in dilute regimes. The consistency between independent experiments and simulations for dilute cases, plus the use of standard Oldroyd-B without fitted parameters for the target result, represents a strength in reproducibility and falsifiability.

major comments (2)
  1. [Experiments section] Experiments on high-concentration regime: the reported sensitivity of pinch-off dynamics to needle size at high polymer concentrations (evident in the regime distinctions drawn from the data) appears post-hoc and load-bearing for the claim that threads require large concentrations; this distinction risks circularity in defining the dilute regime where the Oldroyd-B explanation applies.
  2. [Numerical simulations and analytical modeling] Oldroyd-B modeling and stress singularity analysis: the central claim that polymer stresses are singular yet weaker than in drop pinch-off rests on the constitutive model remaining valid at extreme local extension rates; however, the absence of finite extensibility and shear-thinning (both active at Wi ≫ 1 near pinch-off) could regularize or alter the effective scaling, and no test with FENE-P or similar is provided to confirm the divergence strength.
minor comments (2)
  1. [Methods] Notation for Weissenberg number and relaxation time should be clarified in the methods to avoid ambiguity when comparing bubble and drop cases.
  2. [Figures] Figure captions for the high-concentration needle-size data could explicitly state the number of repeats and error bars to strengthen the regime distinction.

  1. Referee: [Experiments section] Experiments on high-concentration regime: the reported sensitivity of pinch-off dynamics to needle size at high polymer concentrations (evident in the regime distinctions drawn from the data) appears post-hoc and load-bearing for the claim that threads require large concentrations; this distinction risks circularity in defining the dilute regime where the Oldroyd-B explanation applies.

    Authors: We acknowledge that the presentation of the high-concentration regime could give the impression of post-hoc classification. To address this, we have restructured the revised manuscript to define the dilute and concentrated regimes at the outset of the results section using independent criteria: polymer concentration relative to the overlap concentration c* and measured relaxation times from rheology, rather than relying solely on the observed pinch-off behavior. The needle-size sensitivity is now presented as a separate experimental finding that emerges consistently at concentrations above a threshold determined from these rheological data. This removes any circularity and makes the applicability of the Oldroyd-B analysis to the dilute regime explicit and a priori. revision: yes

  2. Referee: [Numerical simulations and analytical modeling] Oldroyd-B modeling and stress singularity analysis: the central claim that polymer stresses are singular yet weaker than in drop pinch-off rests on the constitutive model remaining valid at extreme local extension rates; however, the absence of finite extensibility and shear-thinning (both active at Wi ≫ 1 near pinch-off) could regularize or alter the effective scaling, and no test with FENE-P or similar is provided to confirm the divergence strength.

    Authors: We agree that the Oldroyd-B model has limitations at the extreme extension rates encountered near pinch-off, where finite extensibility and shear-thinning become relevant. Our central claim, however, is restricted to the dilute regime, where the low polymer concentration keeps the effective chain extension within the linear regime for the timescales of interest, allowing Oldroyd-B to capture the weaker stress singularity relative to drops. We have added a dedicated discussion paragraph in the revised manuscript outlining the validity range of Oldroyd-B, the expected qualitative effects of finite extensibility (which would not eliminate the difference from drop pinch-off), and the reasons a full FENE-P comparison lies beyond the present scope. The analytical scaling and numerical results for dilute cases remain robust under these conditions. revision: partial

Circularity Check

0 steps flagged

No circularity: derivation uses standard Oldroyd-B equations and independent experiments

full rationale

The paper derives its central claim—that polymer stresses remain singular during bubble pinch-off but with weaker divergence than in drop pinch-off—directly from numerical simulations and analytical modeling based on the standard Oldroyd-B constitutive model applied to the dilute regime, together with separate experimental observations of thread absence at low concentrations. No load-bearing step reduces to a fitted parameter renamed as a prediction, a self-citation chain, or an ansatz smuggled from prior author work; the Oldroyd-B equations are invoked as an external, established framework rather than defined in terms of the target result. The derivation is therefore self-contained against external benchmarks and does not exhibit any of the enumerated circularity patterns.

    We note that the bubble neck is very slender close to pinch-off, which justifies a slender analysis of the problem

    Elastic stress We will now show why elasticity (in the dilute, Oldroyd-B limit) has little effect on bubble pinch-off, in contrast to the pinch-off of viscoelastic drops. We note that the bubble neck is very slender close to pinch-off, which justifies a slender analysis of the problem. This is in line with the quasi-two dimensional approach for bubble bre...

    To understand this, we first recall the balance of stress for the case of droplet pinch-off

    Pinch-off The interesting situation is thus that the radial stress tends to diverge, but apparently this divergence does not inhibit the collapse of the neck. To understand this, we first recall the balance of stress for the case of droplet pinch-off. The dominant stress in the liquid thread then lies along the axial direction (Fig. 1) and scales asG(h 0/...
