Getting "p" properties at injection from knowing "p" at wall in DEFINE_DPM_BC
Hello everyone !
I'm using DEFINE_DPM_BC to know identify which stream/particle hit my wall and so i can recover the accretion rate for each cell along the wall that was hit. But I also need to know the initial flow rate corresponding to the same particle but at its injection. Basically I need : P_FLOW(p_wall) => I obtain it since my p in DEFINE_DPM_BC correspond to the particle at the wall P_FLOW(p_injection) => with p_injection coming from the same stream than p_wall Do you have any idea how to get it ? |
The macro P_FLOW_RATE(p) gives the injection stream's flow rate [kg/s].

Thanks !
So now I need to divide this mass flow rate by the face area through which the stream is going at injection (first cell). I've identified the first cell(c,t) for each stream and thought using thoes function C_FACE(c,t,i) to identify "f" and C_FACE_THREAD to identify "t" of the specific face and use F_AREA(A,f,t) to obtain the face AREA I need at injection. My problem is the index "i", I don't know its value because I don't know the convention of the index for cell, especially for cell at inlet. Do you have any ideas please ? |
