convection coefficient (h) of the wind
convection coefficient (h) of the wind
(OP)
Hi
I'm working on a heated railway to avoid accumulation of ice and snow.
My intention is to simulate the heat transfer with SolidWork simulation
To do it I need the heat transfer coefficient (h) of the wind from 0km to 100km.
My question is how to calculate the heat transfer coefficient (h) of the wind on a 50km long railway. Can I use simple correlations?
Thanks for your help.

RE: convection coefficient (h) of the wind
Nonetheless, you will be trodding some old ground. SAE AIR 1168-4 Ice, Rain, Fog, and Frost Protection covers the subject of maintaining ice-free conditions on surfaces, albeit, primarily for aircraft surfaces. Table 3F-4, in particular, gives heating loads required to maintain ice-free windshields --> 2.44 W/in^2 for 100 kt cruise speed

RE: convection coefficient (h) of the wind
I have given you a star for answering my question before I even asked it.
I am working on an aircraft engine cowling and the associated airflow for heat rejection. I was googling heat transfer when this popped up.
Thank you.

Just note that that AIR 1168 is actually a 14-volume SAE Aerospace Applied Thermodynamics Manual. Volume 3 Aerothermodynamic Systems Engineering and Design might also be relevant to your efforts.
