flow resistance of cylinder in parallel flow
Hi!
I am looking for literature data for the flow resistance (and heat transfer) of a number of parallel aligned finite length cylinder in turbulent axial flow. It is something like a rod bundle. I need the resistance of the inflow (around the top surfaces), the parallel flow and the outflow (around the back surface). Thank you!! Ralf gas flow . . . . V =>... Length L => ________ => I________I ...... Diameter D => => ________....... Distance A => I________I => => ________ => I________I => => ________ => I________I => 
Have a look in Zukauskas book "Tube Banks in Crossflow" or in his chapter in "Advances in Heat Transfer" 1987.

Hi!
as i understood, this is about cylinder in cross flow. But i need data for cylinder(s) in axial flow! Especially for a larger number of them (something like 100500), aligned axisparallel, depending on the cylinder diameter, the length and the distance between them. The data should include the edges of the cylinder... Thanks.. Ralf 
Sorry, I missed the point that the flow is parallel to the cylinders...
