Role of Magnetic Field in the Redistribution of Turbulence from Large-Scale Structures to Small-Scale Fluctuations

Abhijit Sen, Bhoomi Khodiyar, Lavkesh Lachhvani, Prabal K. Chattopadhyay, Raju Daniel, Rosh Roy, Sayak Bose, Tanmay Karmakar

Increasing the magnetic field from 600 to 1000 G suppresses zonal flows while shifting turbulence power from low to high frequencies through reduced Reynolds stress.

Claims

C1strongest claim

As the magnetic field is increased from 600 to 1000 G, zonal flow is suppressed while the mean flow increases, with spectral analysis showing redistribution of power from low-frequency (0.1-1 kHz) to high-frequency (1-300 kHz) components linked to reduction in Reynolds stress due to loss of correlation between radial and poloidal velocity fluctuations.

C2weakest assumption

The inference that the observed loss of correlation between radial and poloidal velocity fluctuations directly causes the reduction in Reynolds stress and thereby suppresses zonal flow generation; this causal link is stated as 'possibly' in the abstract and rests on the assumption that no other unmeasured factors dominate the change when B is increased.

C3one line summary

Increasing magnetic field strength suppresses zonal flows and redistributes turbulence power from low to high frequencies through reduced Reynolds stress in a linear plasma device.
