How to convert the Reynolds stress into Curvilinear coordinate?
 
Hi,all:
I have just finished a calculation on 90 bend rectangular duct. The experiment data of the Reynolds Stress is in the Curvilinear coordinate, while my calculation is performed in Cartesian coordinate, so I'd like to do a transformation. Considering the 3 components of the velocity fluctuation, u' v' w', we can calculate it from the UPrime2Mean with the operate sqrt. Then do a transformation from Cartesian coordinate to Curvilinear coordinate to obtain the velocity fluctuation in Curvilinear coordinate, say uc' vc' wc'. Is it right?
