svramana is on a distinguished road

i have a problem for which i have not found solution so far.
i have two cubes the smaller one (porous cylinder) surrounded by bigger cube(air)I am trying to setup case which involves conjugate heat transfer from a porous cylinder to surrounding fluid(air) through forced convection.

The cylinder is at constant temperature(600K) and the fluid is incompressible air flowing at a uniform velocity of 1m/s
the flow properties are T air=283, Re=40 ,Pr =0.7 and permeability K=10^-2.

BlockMesh used to mesh the two regions in a single meshing operation, where the internal cylinder is meshed as a cellZone and the porosity is later assigned with an fvOption.

now i need to assign fixed temperature to porous cylinder and simulate heat transfer between cylinder and surrounding fluid.

Can i use fixed temperature constraint(with limited exposure i have, it is applicable to compressible flow)

how to define heat transfer interface conditions between two regions(both are defined as fluids)

Thanks in advance
