Looking through various EN and ISO standards has not helped. If the shaft or hub is blued and fitted together [rotated] a percentage area of the other component is marked.
I am looking for guidance on what would be an acceptable marked area? Some publications for machine tool spindles state 80%...

Hi theonlydave
Thanks for your reply. The rotating drum is in still air except for the fact the action of the rotation will produce forced convection!
I will try to obtain copies of your suggested references. How do you specify the length factor to calculate the Reynolds and Nusselt numbers -...
Can anybody help?
I am trying to find the heat loss from a rotating drum. The following condition would apply - Solid steel drum dia 1m x 0.5m long rotatingi air at 1000rpm. Temperature 100 degC with ambient of 20 degC.
I am finding great difficulty in bringing my distant degree knowledge up to...

I am starting out to find the heat transfer (via convection and radiation) of a rotating steel part say 0.8m dia x 0.5m long at 1000 rpm in air. Temps 100 degC with ambient of 20 degC.
I have studied various text books to bring my long forgotton degree knowledge up to speed. Have you...
