uniformFixedValue和flowRateInletVelocity。 1. uniformFixedValue 这个边界属于第一类边界,即直接指定边界上某个量的值。跟fixedValue的不同之处在于,这个边界条件允许边界上的值随着时间变化。一般的用法如下: typeuniformFixedValue; uniformValuetable ( (0.000 (0 0 0.002)) ...

the comparative analysis of gas-liquid two-phase flow field and concentration field distribution showed that the circulating flow of liquid phase can enhance the local mass transfer efficiency of the column tray, resulting in...
Inlet patch: a flowRateInletVelocity condition was chosen. This allows to define the volumetric or mass flow rate at the inlet patch. Outlet patch: a zeroGradient boundary condition was set. The internal values are therefore extrapolated to the boundary face. dimensions [0 1 -1 0 0 0 0];...
