Scalar dissipation anomaly and scalar-gradient scaling in turbulence: A joint velocity-scalar multifractal view
Dhawal Buaria
We revisit the problem of scalar dissipation anomaly and scaling of scalar gradients in passive scalar turbulence using theory and data from well-resolved direct numerical simulati…
Scalar gradient structure and dynamics in turbulent mixing at high Reynolds and Schmidt numbers
Ruqaiya Islam Mishi, Dhawal Buaria
How well turbulence mixes a scalar is governed by the scalar dissipation rate , making scalar gradients central to turbulent mixing. We study the structure a…
Unified multifractal description of longitudinal and transverse intermittency in fully developed turbulence
Dhawal Buaria
Small-scale intermittency is a defining feature of fully developed fluid turbulence, marked by rare and extreme fluctuations of velocity increments and gradients that defy mean-fie…
Universality of extreme events in turbulent flows
Dhawal Buaria, Alain Pumir
The universality of small scales, a cornerstone of turbulence, has been nominally confirmed for low-order mean-field statistics, such as the energy spectrum. However, small scales…
Twisting vortex lines regularize Navier-Stokes turbulence
Dhawal Buaria, John M. Lawson, Michael Wilczek
Fluid flows are intrinsically characterized via the topology and dynamics of underlying vortex lines. Turbulence in common fluids like water and air, mathematically described by th…
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…
