Hello everyone,

We try to model heat exchange bewteen a fluid and a solid. In order to solve the viscous sublayer we use k-e model with enhanced wall treatement and our grid allow us to get y+ under 5 all along the exchange surface.

We could solve solid and fluid problem together in Fluent but we wish to export HTC from Fluent and send it to Ansys Mechanical.

Unfortunately, HTC is calculated using adjacent temperature and in our case we have Twall almost equal to T_adj_temp. The T_adj_temp isn't representative to Tbulk.

Anyone know how we can get a better estimation of T_bulk ?

Thanks !
