Dependence of heat transfer from a wide copper plate to liquid helium on heat transfer surface orientation and treatment.

Author(s) : IWAMOTO A., MITO T., TAKAHATA K., YANAGI N., YAMAMOTO J.

Summary

The critical heat flux has its maximum between 0 and 30 degrees of the surface orientation, where the angle is taken from the horizontal axis. On the other hand, the minimum heat flux has less dependence on the heat surface orientation. The critical heat fluxes of the 50% oxidized surfaces almost agree with that of the polished copper surface. The minimum heat fluxes of the 50% oxidized copper surfaces approximately agree with that of the 100% oxidized copper surface.
