To study the influence of the exhaust plume on the launching equipment and the environment, the plume of the rocket launching process was researched. The dynamic updating method was used to simulate the launching process of the rocket. The finite volume method was used to calculate the ablation and impact of the plume on the launching equipment. The results show that the flame deflector and first...
A method moving vehicle noise simulation was given. Geometric model of a sedan car is built using Pro/E. Analytical model was built by meshing using GAMBIT. FLUENT was applied to solve the steady simulation using RANS method. The noise source distribution of the vehicle surface is predicted based on the Broadband Noise Source Model. The unsteady simulation is solved using LES method. The far-field...
The main geometric structural parameters which affected the performance of the compression cell of the helico-axial multiphase pump greatly were selected as the research object. The groups of impeller parameters were determined by the orthogonal experimental design method. Then the pressure rise and efficiency for each group which were obtained through numerical simulation according to CFD method...
