Role of pressure in generation of intense velocity gradients in turbulent flows
Dhawal Buaria, Alain Pumir
We investigate the role of pressure, via its Hessian tensor , on amplification of vorticity and strain-rate and contrast it with other inviscid nonlinear mechanisms. Re…
Saturation and multifractality of Lagrangian and Eulerian scaling exponents in 3D isotropic turbulence
Dhawal Buaria, Katepalli R. Sreenivasan
Inertial range scaling exponents for both Lagrangian and Eulerian structure functions are obtained from direct numerical simulations of isotropic turbulence in triply periodic doma…
Forecasting small scale dynamics of fluid turbulence using deep neural networks
Dhawal Buaria, Katepalli R. Sreenivasan
Turbulent flows consist of a wide range of interacting scales. Since the scale range increases as some power of the flow Reynolds number, a faithful simulation of the entire scale…
Comparing velocity and passive scalar statistics in fluid turbulence at high Schmidt numbers and Reynolds numbers
Dhawal Buaria, Katepalli R. Sreenivasan
Recently, Shete et al. [Phys. Rev. Fluids 7, 024601 (2022)] explored the characteristics of passive scalars in the presence of a uniform mean gradient, mixed by stationary isotropi…
Role of initial separation for Richardson scaling of turbulent two-particle dispersion
Dhawal Buaria
The role of initial separation for inertial range scaling of turbulent two-particle dispersion is reassessed in light of recent results. (slightly expanded version of Comment publi…
