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…
Vorticity-strain rate dynamics and the smallest scales of turbulence
Dhawal Buaria, Alain Pumir
Building upon the intrinsic properties of Navier-Stokes dynamics, namely the prevalence of intense vortical structures and the interrelationship between vorticity and strain rate,…
Self-attenuation of extreme events in Navier-Stokes turbulence
Dhawal Buaria, Alain Pumir, Eberhard Bodenschatz
Turbulent fluid flows are ubiquitous in nature and technology, and are mathematically described by the incompressible Navier-Stokes equations (INSE). A hallmark of turbulence is sp…
Vortex stretching and enstrophy production in high Reynolds number turbulence
Dhawal Buaria, Eberhard Bodenschatz, Alain Pumir
An essential ingredient of turbulent flows is the vortex stretching mechanism, which emanates from the non-linear interaction of vorticity and strain-rate tensor and leads to forma…
