孔板对水槽内流场影响规律
Influence laws of pore plates on basin internal flow field
摘要
Abstract
In order to simulate the situation how the vertical tube is washed by the seawater inside the tube, this study is aimed to simulate the ocean advection by using the pore plate structure in a flume. To obtain the stable and uniform velocity field, the FLUENT software is used to simulate the stable velocity field by using the pore plate structure in a flume. The standard κ-ε turbulent model is adopted to analyze the pore diameter, thickness, position and arrangement layers of the pore plate, then the structure of the pore plate is optimized. The simulation results show that, when the orifice plate is not in-stalled, there is a trend of jet and diffusion in the whole tank, but the jet does not drive all the fluid in the tank. Only part of the fluid has the velocity, in the water tank, the lower end has whirlpool and reflux generation, and the velocity distribu-tion is not uniform. It is more favorable to obtain the uniform flow field with three pore plates whose thickness is 0. 2 m, where the interval between them is 0. 3 m,the first pore plate is set to 0. 2 m away from the inlet, and the diameter of the hole on the first pore plate is set to 0. 03 m.关键词
