Abstract
Liquid hydrogen is expected as a coolant for a HTS superconducting magnet because of its excellent cooling properties. However, there has been a lack of an extensive heat transfer data of liquid hydrogen in forced flow condition for superconductor cooling.As a first step of the study, the experimental setup, which can be used for investigating heat transfer characteristics of liquid hydrogen in a pool and also in forced flow for wide range of sub‐coolings, flow velocities and pressures up to supercritical condition, have been designed and fabricated. The mass flow rates during the forced flow tests were measured by the weight change of the main cryostat. All the control valves, the heating control and measuring system were remote‐operated through optical fiber connected computer controls. It was confirmed that the control and measuring systems were operated well as designed.A basic test of heat transfer in liquid hydrogen was carried out by quasi‐steadily increasing heat inputs to horizontal flat plate wi...
