Forced Convective Heat Transfer for moving cylinde
I am interested in estimating the convection heat transfer coefficient of a cylinder moving in water. The length of the cynlinder can be taken as L and diameter as D and L/D ~ 2. The cylinder speed may be taken as 15 m/s.
I would be grateful if someone could suggest me an empirical technique/ formulae with theory for estimating the same. thanx in advance

Set up a simple model with fixed cylinder & moving water (relativitity). You can tackle the heat input in 2 ways: 1. Macro  measure overall water temperature diffeence up & downstream & compute the heattransfer. Work backwards to calculate the average heattransfer coefficient. 2. Surface  from the solution, compute the surface temperature gradient & then onto the local & average surface heattransfer coefficient. Some packages will even allow the user to collect the surface fluxes. >>>I would be grateful if someone could suggest me an empirical technique/ formulae with theory for estimating the same. These can be found in almost any standard college theattransfer textbook. "Fundamentals of Heat & Mass Transfer", Incropera & Dewitt, is a good one. Bejan has a few good books. diaw...
