khoopes is on a distinguished road
I am doing a conjugate heat transfer model of flow in the back cavity of an centrifugal impeller. In the fluid models page of CFX-Pre there is an option: Turbulent Flux Closure. I have been reading in the help about it, but it does not give a recommendation on when to enable it. Does anything have any experience with this option to know what is advisable?

The only thing I can see under that option is the Prandtl number - you don't want to adjust that, it is one of the key constants in the turbulence model. When the option is not selected then it uses the default Prandtl Number. To change it you activate the option. But to change it requires either bravery or naivety.
