Hey I want to introduce moisture over a surface. I have been writing a UDF for this.
Two fluids One is air & other is Licl both are stacked to each other with a membrane & its shadow between two. Now i want moisture content in the air on the membrane surface in the air side. I have been using coupled wall option in which trying to load udf but someone is suggesting me to load udf in air cell zones by using defining source. I am confused please help me out. And in loading on coupled wall option, nothing on the membrane surface.


Please help me out in this step.

#include "udf.h"

DEFINE_PROFILE(mass_h2o,t,i)
{
cell_t c;
Thread *t;
int i;

real x[ND_ND];
real A[ND_ND],At;
real x_H2O;

begin_f_loop(f,t)
{
F_AREA(A,f,memb_thread);
At=NV_MAG(A);
F_CENTROID(x,f,t);
F_YI(f,t,0);

F_PROFILE(f,t,i)=F_YI(f,t,0);
}
end_f_loop(f,t)
}

Some one is saying me to do through using Source terms.



Seniors please give me your insights over this.

Regards,

Abbas Raza
