Thank You.

There, you will find Nusselt number results for experimental data. Best Regards!

In the purest sense, you have a slab, one end Dirichet BC and at the other, Neumann. Would be easy to generate simulation cases but you would need to use expansion methods to solve it analytically. See the time transient slab validations on our validation page. regards SSD
