Reynolds and Turbulent Flow

Frederic Dubinski

Hi,

I've got two questions here. I would be very pleased if someone could answer them!! Thanks

Q1--If during your analysis, you find that that Reynolds number changes the flow from laminar to turbulent as the water flows around the cooling jacket circumference, say half way round; Then would you change the calculation so that the rest was performed with a turbulent flow model.? Or would you leave it to calculate the rest still using a laminar flow model.

Q2--Can CFX cope well with flow regimes that vary in nature. "What does it do" so to speak.?

i.e. A flow that changes from laminar to transition and then turbulent flow during the flow path.?
