Solid State Temperature
 

Hi,
I am working on porous media with local thermal non equilibrium model.

I do not know how can I define solid state temperature.

I found UDS code for solid diffusivity and and source code. But solid state temperature Ts was not defined.

Where can I define solid temperature.

if you help I would be glad.

This is Uds code for diffusivity.

#include "udf.h"
#define TKS 10
#define SOLID_THERMAL_COND(Ts) 2
#define SOLID_DENSITY(Ts) 3
#define SOLID_CP(Ts) 2



enum { SOLID_TEMP };

DEFINE_DIFFUSIVITY( uds_diffusivity, cell, thread, i )
{

real source;
real Ts;

if (i == SOLID_TEMP)

{

Ts = C_UDSI(cell, thread, SOLID_TEMP);

source = (SOLID_THERMAL_COND(Ts) / (SOLID_DENSITY(Ts)*SOLID_CP(Ts)));

}

else source = 0.0;

return source;
}
