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…
A highly scalable particle tracking algorithm using partitioned global address space (PGAS) programming for extreme-scale turbulence simulations
Dhawal Buaria, P. K. Yeung
A new parallel algorithm utilizing partitioned global address space (PGAS) programming model to achieve high scalability is reported for particle tracking in direct numerical simul…
Small-scale isotropy and ramp-cliff structures in scalar turbulence
Dhawal Buaria, Matthew P. Clay, Katepalli R. Sreenivasan +1
Passive scalars advected by three-dimensional Navier-Stokes turbulence exhibit a fundamental anomaly in odd-order moments because of the characteristic ramp-cliff structures, viola…
Dissipation range of the energy spectrum in high Reynolds number turbulence
Dhawal Buaria, Katepalli R. Sreenivasan
We seek to understand the kinetic energy spectrum in the dissipation range of fully developed turbulence. The data are obtained by direct numerical simulations (DNS) of forced Navi…
Turbulence is an ineffective mixer when Schmidt numbers are large
Dhawal Buaria, Matthew P. Clay, Katepalli R. Sreenivasan +1
We solve the advection-diffusion equation for a stochastically stationary passive scalar , in conjunction with forced 3D Navier-Stokes equations, using direct numerical simulati…
