Modeling Cryogenic Chilldown Of A Transfer Line With The Generalized Fluid System Simulation Program

Abstract

This paper describes a computational thermofluid model of the chilldown of a transfer line by a cryogenic fluid. Accurate modeling of the chilldown process is desirable to develop loading procedures that minimize propellant loss; however, accuracy has been impeded by uncertainty in boiling heat transfer correlations at cryogenic temperatures. The University of Florida has developed a new chilldown boiling correlation from a series of cryogenic experiments with liquid nitrogen and liquid hydrogen. This correlation has been coded as a Fortran user subroutine in the Generalized Fluid System Simulation Program, a general-purpose network flow analysis code. The model’s predicted wall temperatures are compared to test data, as well as to predictions by other heat transfer correlations.
