Intensity and regimes changing of hydrodynamic cavitation considering temperature effects

Venturi-type cavitation reactors still appear as the most promising candidates for industrial-scale production due to their cheapness and ease of construction, scaling, replicability. The effects temperature on hydrodynamic cavitating flows in a Venturi section are investigated find optimum reacting conditions enhancing treatment intensity. flow varied with 4 different rates wide range temperatures between 28 ? 63 ?. Results show that both length transition sheet cloud regimes influenced by combination pressure drop (indicated number ?), inertial/viscous (controlled Reynolds Re), thermal effect thermodynamic parameter ?). As is elevated, thickness increase first, then decrease. intensity peaks at 58 With thickness, tend switch earlier from attached cavity periodical shedding, shedding frequency decreases accordingly. When progressively increased, changing structures illustrated through Proper Order Decomposition analysis. This study allows us understand instability, size evolution, regime partial cavities considering effects.
