Vapour flows and heat conductances in ventilated cavities behind a two-dimensional cylinder. Part 1: Review of entrainment and thermodynamic effect; viscous effects on limited and developed cavitation
Abstract
Types of gas and vapor entrainment found in natural and ventilated cavity flows about circular and certain other bluffed bodies are discussed. Methods for analyzing the thermodynamic effect are reviewed and, on the basis of an analysis using entrainment theory, it is that vapor ventilation offers advantages over foreign gas ventilation techniques. Experiments were performed, using a high temperature cavitation tunnel, that show strong viscous effects on cavitation inception form for both limited and developed cavitating flow regimes.
