Kilowatt Isotope Power System, Phase II Plan. Appendix A to Volume II and Volume III: KIPS Jet Condenser Math Model

摘要

The analytical model of the condensation process occurring in a jet condenser that was developed during Phase I of the Kilowatt Isotope Power System Program (KIPS) at Sunstrand Corporation is documented. The analytical model is based on one dimensional gas dynamics in the vapor funnel, a kinetic theory approach to the vapor/liquid interface condensing process and an empirical correlation of the intrajet heat transfer coefficient (from the vapor/liquid interface to the bulk liquid in the jet). This model satisfactorily predicts the measured performance of the KIPS jet condenser. The first section of this KIPS jet condenser report presents the KIPS jet condenser development history from the beginning of the program (August 1975) through February 1977, at which time it was apparent that the initial design was underperforming slightly. It was decided that an improved analytical model would be beneficial. The subsequent sections deal with the development of the basic experimental data taken on a variety of single jets in a steam/water jet condensation rig to obtain the intrajet heat transfer coefficients required by the analytical model. Also included is a section describing the experiments conducted on the jet condenser to determine the limit conditions under which jet condenser floodout can occur. (ERA citation 05:037777)
