I'm sorry for the late reply, OJ. Do you have a source for the bit I've bolded above? Naturally I've tried to search through the theory guides, and text books to no avail.

Hi, thanks - but I knew that the solver Re is a red herring! I physically went into CFD post and calculated my Re and Ra numbers based on the post processed data.

I agree with you oj.bulmer and ghorrocks. I am monitoring the Rayleigh number. As a general rule of thumb anything below 10^8 is laminar, anything above 10^10 is turbulent. My flow sits at 10^9! ...

Replies: 7 Ratio of eddy viscosity to molecular viscosity : Laminar or turbulent flow? Views: 12,733 Posted By JuPa Ratio of eddy viscosity to molecular viscosity : Laminar or turbulent flow? I'm stuck between a rock and a hard place. I'm modelling a differently heated cavity, which induces density variations and causes the fluid to recirculate. I've tried laminar and turbulent...
