Abstract
The present study emphasized on the information of cavitations during the dual phase flow i.e. (water and vapor) in venture converge-diverge nozzle. The choice of nozzle with a transparent material (PMMA), was found suitable for the observation and measurements. The model of this problem of defining dual compressible viscous flow, and k-epsilon model. The comparisons of numerical calculation and experimental observation were found to be comparatively coincidable in cavitational zone and throat pressure, and fractional phase flow.
