STEPAC-an SP-100 thermoelectric-electromagnetic pump analysis code

The reference flight system design of the SP-100 power system uses thermoelectric-electromagnetic (TEM) pumps to circulate its coolants. To predict the performance and estimate the mass of these pumps, an integrated computer model has been developed. This computer code, dubbed STEPAC, models the coupled thermal, magnetic, hydraulic and electrical aspects of the pump. The code incorporates a magnetic fringe model and a current-dependent magnetic field strength model, both in conjunction with the Poisson magnetostatic code. STEPAC was used to predict the performance of the RFS SP-100 TEM pump. The results of several scoping parametric studies are presented.<
