I am trying to solve this problem using advection-diffusion model and finite element method for the solution, due to the complex geometry.
Basically the problem i'm trying to solve using OpenFOAM is see how heat is distributed when fan is placed on a heated power source, and how much speed or how many fans should be placed.
First, i'm thinking first about the advection-diffusion model for this, is it the proper model ?
Second, how about stokes equations (they are hyperbolic) , how would heat be expressed ? (They're not suited for the heat problem, if i'm not mistaken)
