Normal particle velocity in particle deposition!
I am working on building a deposition model using UDF in fluent. My criteria for particle sticking compares the particle critical velocity with the particle normal velocity. How do I get the normal velocity in my UDF? Is it just the velocity in the direction normal to the wall or would I have to use something like the code below to find it? This was taken from the UDF manual example.
alpha = M_PI/2. - acos(MAX(-1.,MIN(1.,NV_DOT(normal,p->state.V)/
if ((NNULLP(t)) && (THREAD_TYPE(t) == THREAD_F_WALL))
/*computing normal velocity*/
vn += p->state.V[i]*normal[i];
