Abstract

We investigate the flow of a foam injected through a cylindrical inlet into a quiescent liquid which is miscible with the foaming solution. Depending on a Reynolds number, combining inlet diameter, liquid viscosity, and flow rate, the jet disperses into a conical plume, takes a stable cylindrical straight shape whose radius swells with flow rate or disintegrates into blobs. We compare this behavior to that reported for other complex fluid jets and present a simple physical model for the straight jet regime.
