Abstract
A theory was developedf or cavitation flow in a two-dimensional right-angled branch duct. In analysis, the wake model was used. As a numerical example, the shape of the cavity streamline originating from the branch corner, the length of the cavity and the cavity height (thickness) were obtained for the values of 0.5, 1.0 and 2.0, which was the width ratio of the main duct to the lateral duct. The length and thickness of the resulting cavity were determined as a function of the cavitation parameter and the velocity of the lateral stream to the mainstream. That is, the length and thickness of the cavity increased as the cavitation parameter and the velocity ratio decreased, and as a result, the flow width of the lateral duct decreased. The cavitation parameters on the condition of the supercavitation were increased as the velocity ratio decreased a, nd these parameters agreed well with experimental results of the author's previous paper.
