这个边界条件指定的是界面上的体积流量或者质量流量,并根据流量来反推速度。速度的方向为垂直边界并指向区域内部。一般的用法如下: myPatch { type flowRateInletVelocity; volumetricFlowRate 0.2; //体积流量 value uniform (0 0 0); } myPatch { type flowRateInletVelocity; massFlowRate 0.2; //质量流量 rho...

rate， k指的是turbulence kinetic energy，mut指的是turbulence viscosity，同时alphat, epsilon, k, mut 这个⼏个参数都是要给定壁⾯条件模型的。像其他的tutorial例⼦中给出的也都是速度进⼝边界条件，跟我的算例所需要的压⼒进⼝边界条件不太吻合。好在OpenFoam给出了各种不同类型的边界条件类型供...

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];...
