Hello,

I wanted to simulate a cylinder head water jacket(just single cylinder head). Steady state simulations, to check the temperatures on the cylinder head parts after the water jacket simulations.

I have a solid parts and a liquid Region(one solid-liquid inetrface)

i have did simulations by modelling with convection as thermal specifications.but the model is not working.

i have a massflow inlet, pressure oulet.
i have defined the solid parts directly with final temperatures(solid block, combustion chamber head, inlet and exhaust valve rings).

sugesst me about the modelling for the CHT.

thanks in advance.

Do you have a question?

My question is shall i use Heat flux instead of convection in thermal specifications to model the solid Region.?

what i understood is you have two regions (solid and liquid) then the thermal specification of the interface should be set to conjugate heat transfer, and the thermal specifaction of boundary will be inactive.

If you have a solid region then the interface between the fluid/solid needs no special boundary condition.

As for heat input into the solid (if it doesn't come from the fluid), that's up to you and your application. Nobody can tell you if heat flux or convection is a better model of your physical system.

Thanks for the reply.
