heat transfer coefficient; melting snow and ice
heat transfer coefficient; melting snow and ice
(OP)
I am working on a problem that involves heat generation to maintain the melting of snow and ice. Would it be correct to use a film coeficient of water at a constant 0 degree C temp. With this method I will be neglecting air temp less than 0, my worst case condition is around -40 C.
Thanks in advance

Bottomline, if you can't get access to the SAE documents, is that you need something like 1 w/in^2 to 2 W/in^2 for a moderate wind and moderate deicing time. Volume 4, Table 3F-3 on page 41, shows power values up to 4 W/in^2 for 300 kt air speed, which, hopefully is outside of your application.
