Instability of an active fluid jet

Physical Review Fluids, vol. 7

Abstract

Instabilities of an active fluid jet (Center) are investigated. Left: For an active fluid of pullers, the jet breaks up into droplets in a varicose manner reminiscent of a Newtonian fluid. Right: For pushers, on the other hand, the jet buckles and undergoes a waving instability.
