Boundary Conditions for Residence Time Distribution in Ozone Contactor

Hi,
I am doing a CFD study of an Ozone Contactor for disinfection of water. I am using the UDF for diffusivity of water found in the Fluent manual: #include "udf.h" DEFINE_DIFFUSIVITY(mean_age_diff,c,t,i) { return C_R(c,t) * 2.3e-09 + C_MU_EFF(c,t) / 0.7; } I need to use the Pulse Method for the transient solution to determine the Residence Time Distribution. However, I am confused with generally how to set up the Boundary Conditions, and whether I should be using Species Transport if I am using UDS? Finally, when creating the patch, is it okay just to have the whole Inlet as the 'Zone to Patch'? Thank you in advance. |
