Pressure and tension in momentum-conserving active fluids

ORAL

Abstract

We consider a fluid governed by the Navier-Stokes equation, driven by stresses carried by a suspension of rotationally diffusing self-propelled objects. We present results on the scale-dependence of the steady-state pressure and the dynamics of fluid interfaces in such a system.
