Abstract
Gas-liquid turbulent two phase flow along a vertical flat plate with gas evolution was numerically simulated with a two-fluid model and Plandtl’s mixing length theory using the SIMPLER method. The calculation domain was assumed to be two-dimensional and gas bubbles to be evolved uniformly from the plate surface. The computed velocity profiles were affected by void fraction on the wall and the bubble diameters, but not by the bubble departure velocity from the plate surface. Both the gas and liquid velocity profiles and the computed wall shear stress with the present model were qualitatively and quantitatively coincident with those measured using LDV for the vertical flat plate electrode with H2 or O2 gas evolution.
