abstract
We revisit the problem of proving the incompressible limit for the compressible porous media equation with Newtonian drift and growth. The question is motivated by models of living tissues development including chemotaxis. We extend the problem, already treated by the authors and several other contributions, in using a simplified approach, in treating dimensions two or higher, and in incorporating the pressure driven growth term. We also complete the analysis with stronger $L^4$ estimates on the pressure gradient. The major difficulty is to prove the strong convergence of the pressure gradient which is obtained here by a new observation on an algebraic relation involving the pressure gradient for weak limits.

Hele-Shaw limit of chemotaxis-Navier-Stokes flows
For the chemotaxis-Navier-Stokes system with porous medium diffusion, as m→∞ the solutions converge to a Hele-Shaw free boundary problem whose pressure satisfies the complementarity relation P∞(ΔP∞ − ∇·(χ(c∞)∇c∞))=0.
