Fundamental Studies in Hydrogen Blow-Down and Cryogenic Cooling

Abstract

A hydrogen facility designed to conduct experiments relating to blow- down of supercritical hydrogen is described in detail. A theoretical study was conducted to determine the best way of supplying supercritical hydrogen at specified temperature and pressure; the different methods of meeting the required experimental criteria are discussed. The latter part of the study describes experimental arrangements designed and fabricated to study the fluid flow phenomena in free expansion of supercritical/liquid cryogens, and the heat transfer characteristics of cryogens under spray cooling and jet impingement.
