发布时间：2019-02-28 11:10
【摘要】：以实际水池造流系统为例,采用两相流瞬态模拟对水池内的速度场进行了模拟,并将结果与单相流的简化模型进行了对比。结果表明:无滑移壁面和无剪切力壁面两种方法的模拟结果较其使用两相流方法分别小10.8%和5.7%。另外,水池中的流态发展将会产生漩涡,并影响出流的角度,而这一过程需要一定时间才能达到动态平衡。
[Abstract]:Taking the actual pool flow system as an example, the velocity field in the pool is simulated by the transient simulation of two-phase flow, and the results are compared with the simplified model of the single-phase flow. The results show that the simulation results of non-slip wall and shear-free wall are 10.8% and 5.7% less than those of the two-phase flow method, respectively. In addition, the development of the flow pattern in the pool will produce whirlpool and affect the angle of the outflow, and this process will take a certain time to achieve the dynamic equilibrium.
