摘要： 利用通用有限元分析软件ANSYS中的计算流体动力学模块(FLOTRANCFD),对浸没循环撞击流反应器(简称SCISR)的流场进行了模拟和分析·计算结果表明,SCISR流场中各参数关于撞击面完全对称;导流筒上下两侧及撞击区内仍然有死区存在,可以通过增加雷诺数来减小·在撞击区内速度等值线比较密集,即这个区速度梯度比较大,这对于促进湍动混合非常有利·最后,应用计算机压力采集装置对流场进行了压力测试,并与模拟结果进行了比较·

Abstract: Uses the module FLOTRAN CFD for hydrodynamic computation in the software ANSYS that is versatile to finite element analysis to model and analyze the flow field of the submerged circulative reactor to impinging streams (SCISR). The computation results showed that all the parameters in the flow field are symmetrical to the planes impinged. It was found that there are still dead zones on upper and lower sides of conversion barrel and in impinging zone, but they can be reduced by increasing Reynolds number. In the impinging zone the velocity isolines are intensive, ie., in the zone there is a great velocity gradient which is very beneficial to mix up turbulent motions. A pressure value acquisition device on computer is applied to conduct pressure testing for the flow field and the pressure values measured are compared to that modeled, with a good compliance shown.
