Turbulence and heat transfer on a rotating, heated half soap bubble
X. Q. HE, A. D. Bragg, Y. L. Xiong +1
We use Direct Numerical Simulations to study the two-dimensional flow of a rotating, half soap bubble that is heated at its equator. The heating produces buoyancy and rotation gene…
Mechanisms governing the settling velocities and spatial distributions of inertial particles in wall-bounded turbulence
Andrew D Bragg, David H Richter, Guiquan Wang
We use theory and Direct Numerical Simulations (DNS) to explore the average vertical velocities and spatial distributions of inertial particles settling in a wall-bounded turbulent…
Exploring the turbulent velocity gradients at different scales from the perspective of the strain-rate eigenframe
Josin Tom, Maurizio Carbone, Andrew D Bragg
Expressing the evolution equations for the filtered velocity gradient tensor (FVGT) in the strain-rate eigenframe provides an insightful way to disentangle and understand various p…
Fluctuation-theorem and extended thermodynamics of turbulence
Amilcare Porporato, Milad Hooshyar, Andrew D Bragg +1
Turbulent flows are out-of-equilibrium because the energy supply at large scales and its dissipation by viscosity at small scales create a net transfer of energy among all scales.…
