Abstract

Simple shear flows of dilute suspensions of spherical bubbles at large Reynolds numbers are studied by using numerical simulations and kinetic theory. It is shown that the mean-square bubble velocity is very sensitive to the volume fraction and Reynolds number of the bubbles as well as on initial conditions. The balance of energy contained in bubble velocity fluctuations plays an important role in the rheology of the dispersed phase, which is generally non-Newtonian.
