Introduction
This tutorial examines the the flow of water around a torpedo. Cavitation occurs in many applications as a result of flow acceleration over a body surface. Vapor production is localized at the wall where the pressure is below the vaporization pressure, so grid refinement and the use of non-equilibrium wall functions improve the accuracy of the simulation.
This tutorial examines the the flow of water around a torpedo. Cavitation occurs in many applications as a result of flow acceleration over a body surface. Vapor production is localized at the wall where the pressure is below the vaporization pressure, so grid refinement and the use of non-equilibrium wall functions improve the accuracy of the simulation.
The case is taken from a paper by Kunz et al. Using FLUENT's multiphase modeling capability, you will be able to predict the inception of cavitation near the nose of the torpedo.
Problem Description
Problem Description
The problem considers the cavitation caused by the flow of water around a torpedo at an incidence angle of zero and a free-stream velocity of 1 m/s.
The torpedo diameter is 0.136 m. The geometry of the torpedo is shown in Figure.
