Convective heat transfer coefficient for air
(OP)
Where could I find some values for the heat transfer coefficient for air under natural convection? I have to believe that this has been worked out many times somewhere.

I use formulae from McAdams Heat Transmission, which gives h=1.776(DT)^0.25 for air for a vertical surface.

However, your mileage may vary, so you can, and should, calculate it for your specific scenario: http://en.wikipedia.org/wiki/Natural_convection

J.P.Holman's Heat Transfer McGraw-Hill, Para. 7-9 (Table 7-2) gives simplified equations for free convection from various surfaces for laminar and turbulent flow.

The formulae, calculations, etc, are from Fundamentals of Heat and Mass Transfer by Incropera and DeWitt.

There's nothing like starting up a sulphur plant in central Alberta in January, for example.
