Numerical Modeling of Thermofluid Transients During Chilldown of Cryogenic Transfer Lines 2003-01-2662

This paper describes the application of a finite volume procedure for a fluid network to predict thermofluid transients during chilldown of cryogenic transfer lines. The conservation equations of mass, momentum, and energy and the equation of state for real fluids are solved in a fluid network consisting of nodes and branches. The numerical procedure is capable of modeling phase change and heat transfer between solid and fluid. This paper also presents the numerical solution of pressure surges during rapid valve opening without heat transfer. The numerical predictions of the chilldown process have been compared with experimental data.
