Model settings for lower Re flow?
 

I am modeling a heated flat plate. I have boundary layers on the plate(12 layers .005" for the first and 1.1 growth factor) and and using k-e model. My model gives decent results at the higher Re numbers but does not at the lower ones. My lowest Re number is about 6000 in the channel part of the model. Does anyone know what could be causing this and if so what to do about it. It would be greatly appreciated. Thanks!

all of the K-epsilon model is not suitable for the low Re condition.

change it to something else.:)

Any suggestions for which model would be best?
