Question about Eulerian Boiling UDF
 

hellow. Thanks for your attention of this question.

Recently, i try to simulate CHF with the Eulerian-Boiling-CHF model.

Within the "phase interaction-mass-boiling" Tab, i want to change the original "Bubble departure frequency" with a udf model.

but there is a question confused me, i have to use the "bubble departure diameter" in my udf, the "bubble departure diameter" is modeled with unal model.

how can i get access to the parameter in my udf? i have found that the "saturation temperature" is available by the way like :

real sat_T = C_STORAGE_R(c,t,SV_SAT_TEMPERATURE)

so, i'm thinking if there is a similar form to get the "bubble departure diameter", and i've tried several forms but all failed.

I'm really appreciated for your help or advice!:)

Hi, have you figured out how to solve this problem?
