Dear Foamers

Im looking for a way to simplify my simulation problem. I have a a very complex geometry which i solve with chtMultiRegionSimpleFoam. It has two air domain regions, one with forced and one with natural convection. There is also a solid region in between which has a complex water cooling channels inside. Im looking for a way to avoid modeling the detailed channels and actual water. I want use a bundary condition applied to a simplified uniform channel instead (accuracy of results is not a priority here). I know both water inlet/outlet temperatures, total surface area of the channels and the flowrate. Can anybody please point me into right direction with this? I use foam extend 3.1. I have read that groovyBC could be used for that, but couldnt find a good match for my case in setting such boundary condition.
I attach a simple drawing which could help to understand my problem.

Thanks in advance!
