Is boiling good for convective heat transfer?

Let's say we have a turbulent flow (water at the temperature of 25 degrees Celsius) over a heated block at atmospheric pressure. Now if at the solid-liquid interface the local temperature is...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
