Navier-Stokes and Natural Convection, steady state possible?

[lazyTom]

Hi all,

Not being familiar with CFD and thermal simulation I have a very basic question, is it possible to do steady state simulations on natural convection with Navier-Stokes solver?

On the test cases I was able to find only transient examples, hence the question.

Thanks,

Marco

It is possible if there is a steady state that exists. With flow and convections, if the flow is turbulent then there may not exist a steady state. If the flow is laminar than there could be a steady state. Depending on your model a steady state may converge or may not if there physically is no steady state in the system. Convection is another form of loading causing flow, it could be steady or turbulent.

Tutorial 9 page 44 is a steady state flow problem.

This case at the last post has a steady state convection problem.

Ahi... It's getting complicated
