SubscriberI want to set up a two phase cooling solution for a tube cooled by the inside, in wich the convective heat transfer coefficent  of the solid/liquid surface cells changes, depending on the flow regime, and on a user-defined set of heat transfer correlation. Can i manually do that using an if or when loop?
Thanks!

Ansys EmployeeYes, you can set up a two-phase cooling simulation. You can achieve this by writing a UDF that updates the HTC based on the flow conditions at each time step or iteration. Use a UDF to calculate the HTC based on the local flow conditions, such as Reynolds number, Nusselt number, or any other relevant parameters

SubscriberThanks for the reply!Â
In my case i have to select each time some fluid and solid elements, take the paramenters of interest, and put them as argument of the HT coeff function. For example:
HT coeff at location z = 10m and time t = 2s must be a function of the delta T between liquuid and solid element placed at locazion z at time t
is it possible?Â
Thanks again!
