Abstract:

Solutions are developed for a one dimensional compressible gas bubble-liquid mixture flow through a converging-diverging nozzle. Gas is assumed in the form of spherical bubbles that do not exchange mass with the liquid, but allowance is made for a differential between bubble and liquid velocities. The critical condition for the specified initial flow conditions is found by iteration to establish the local slope of the nozzle wall at each step near the throat, and thus the critical throat is designed uniquely for each flow. Assuming adiabatic expansion for the air bubbles critical and supercritical solutions are obtained for a few specified initial conditions. A choking condition is noted at the section just upstream of the geometric throat of the nozzle. Author
