    What is the film coefficient for a hot object moving through open air?

    I'm well aware that the problem is one of convection not conduction as are the references on heat exchangers I've been reading. Out of 60 or so scenarios that are listed, the one that seems to be of closest relevance is turbulent flow of a cold gas over a "warm wall". In this case the...

    What is the film coefficient for a hot object moving through open air?

    I'm trying to estimate the heat transfer coefficient from the surface of a hot object moving through open air. After much searching, all I can find is coefficients for sundry fluids confined within the tubes of heat exchangers. I'm trying to calculate for a body at between 300-460K moving at...
