Original abstract
Following paper investigates the pressure waves and the dynamics of the vapor shedding mechanism in a converging-diverging Venturi nozzle with the use of Computational Fluid Dynamics (CFD). The study investigates the impact of various turbulence models, providing insights into the accuracy and reliability of different models in predicting vapor shedding mechanisms and resulting pressure fluctuations. The Shear Stress Transport (SST) k-omega, SST k-omega with modified turbulent viscosity and Stress-blended eddy simulation (SBES) were analysed. Also, to accurately capture the resulting pressure waves and the supersonic flow in the liquid-vapor mixture, both vapor and fluid is considered compressible.
