Numerical Simulation of Cavitation and Vapor Bubble Formed in Transient Mode for 3D Marine Diesel Engine Injector Nozzle
In this paper, the velocity graph is used in terms of Crankshaft variation to obtain the pressure graph according to the time of spraying fuel. Time dependent boundary conditions are used with ANSYS FLUENT17.1 software and C ++ programming code. For mesh independent study, has been used eight different meshes, resulting in an optimal mesh with 1520400 points. For code validation, comparison numerical results with the experimental results show good agreements for two-dimensional model. Three-dimensional analysis for different conditions of input and output pressure and the representation of the cavitation contour for the 3-phase mode, with the accuracy of solving the equations of third-order flux vector matrix are done for achieve to the accuracy of the convergence 10-6 and obtaining the mesh node values, and, lastly, corrosion and effects of It has been discussed
