Evaluation of utau
I am simulating turbulent duct flow and wish to calculate Utau.
If I have a cell in the viscous sublayer I can use Newtons law to get Utau.
If I do not have a cell in the viscous sublayer I can use Newton - Raphson and the log-law assumption to obtain a Utau value.
The problem is if one method gives a utau value indicating that the first cell is in the viscous sublayer and the other puts the cell outside the viscous sublayer which do I use ????
I have heard of a method using the local reynolds number - ie if Re_local < magic number then use Newtons law...
does anyone have any ideas?
Thanks in advance
