Abstract

Experimental tests to verify heat transfer effectiveness from heated plates to pressurized liquid hydrogen were conducted. These tests were intended to model a high purity aluminum inductor coil designed to be cooled by flowing liquid hydrogen over the coil’s conductor surfaces. A flow test apparatus was constructed to simulate the surface cooling of the coil. Liquid hydrogen at 7 to 10 atm pressure was directed through flow channels. Variables within the experiment included plate surface heat flux, liquid hydrogen velocity, flow channel thickness and supply tank pressure. Values of film ΔT as a function of plate surface heat flux for different flow rates are compared to analytical calculations.
