Optimization of Rankine Space Power Conversion Systems with the codes ALKASYS-SRPS and DAKOTA

摘要

Mass optimization calculations have been completed with the codes ALKASYS-SRPS and DAKOTA for a Rankine space power conversion system with a power level of 100 kW(e). The parameters varied in this optimization are material of the primary and secondary loops and the hot (turbine inlet) and cold (condenser) temperatures of the system. The optimums (lowest mass) were calculated to be 2336 kg (for a single 100% unit) and 3114 kg (for 2x100% units) for systems employing Nb-1Zr material with a hot temperature (boiler outlet) of 1306 K and a cold temperature (condenser) of 881 K.
