Hi, I am in a Heat Transfer class at school and my professor has set an interesting challenge before me. It is not a homework problem or anything, just a side project he challenged us to look into relating to external flow. The question is as follows: In fluid (e.g air, water) flow over a flat plate, if all that is given is the local Reynolds number Rex at some distance from the edge of the plate, is it possible to calculate the local heat transfer coefficient h at that point? Is there some form an equation for Reynold's number that can relate to the heat transfer coefficient h? If I knew the thermal coefficient k I could use the Nusselt number equation and Reynolds number to solve for h, but all I know is the local Reynold's number. Any suggestions/help? Where I can find the answer or how to derive some equation that will work? I'm actually kind of interested in this so it would be cool to actually figure out. Thanks!
