Studies of cryogenic liquid boiling in centrifugal acceleration fields
Abstract
Current rapid progress in cryogenic power engineering has aroused a tremendous interest in heat transfer in cryogenic liquid boiling in the field of centrifugal forces. In this paper, heat transfer and critical heat flux densities are experimentally studied under nucleate boiling of helium and nitrogen in the field of centrifugal forces. The discussion concerns experimental equipment and results, temperature field in liquid, inception of nucleate boiling, heat transfer, and critical heat flux. The increase in heat transfer coefficients with rising gravity levels is found to result from an increase in the liquid pressure at the heater. The quantitative dependence of the critical heat flux density on the relative acceleration is established for helium and nitrogen.
