| Abstract: | This essay mainly analyses the question about empty cavity towing and flowing and the fluid is water. In this essay , numerical analysis method is SIMPLE, based on which the velocity and temperature in empty cavity under various towing speed is calculated and the isotherm and the vectorgraph of the velocity are given also. Then, the effect that various towing speeds make on the velocity and temperature in empty cavity is analyzed.Finally,We use the CFD software to simulate this problem,compare the two resul... |
