resources available?
 

Thanks for the responses to my previous message on square cylinder in channel flow. I have managed to find a journal on flow past square cylinder describing its streamfunction and vorticity contours. But as I have heard before, but am not sure about it, there seem to be little information available regarding this flow at low Reynolds numbers, particularly from 5 to 30, where no vortex shedding is observed. I need to find the lift and drag coefficients at this Reynolds range. Please advise and thanks again!

There are a few articles on this problems. In these articles you will find lift drag coefficients for this problem for both 2D and 3D flow for Reynold's Numbers of 20 and 100.

At this Reynolds Number, low Mach Number and with a strongly Newtonian fluid (could substitute other fluids if the model was known to be very accurate) any consistent scheme with a high resolution and sound boundary conditions is going to produce:

(a) more accurate information than an experiment

(b) informatation everywhere about everything

I suspect that if you find (modern) experimental information for this flow it will have been conducted to check experimental technique against a numerical prediction.

Many standard test cases such as this have highly refined numerical solutions made available for people to check their predictions against. I am not aware of any for this particular test case but would guess they probably exist. It may be a more fruitful line to pursue.
