I'm doing a cooling simulation of an electric motor that uses a water cooling system. but it seems there is a problem between solid to fluid domain interactions. where when heat flux is applied to the solid domain and propagates to the fluid domain, the results are invalid. but when my inter-domain connection is broken and heat flux is applied to the fluid domain, the result becomes valid
Does anyone know how to maximize heat transfer between solid and fluid domains so that the Nusselt number results are valid? |

for example, on Re 500, the fluid outlet temperature is correct, but the wall temperature is still wrong, what should be 109 C, I got 138 deg C instead, so the Nusselt value should be 12, I got 5 instead. if each domain has a coupled wall and heat transfer has occurred, then where might the problem occur? for the record I've tried smoothing the mesh for the fluid domain |
