| Abstract: | With establishment of a static model for natural circulation loops,and with considering the unique variation of thermo-physical properties under supercritical pressures,this paper,by applying appropriate nonlinear numerical computation based on continuation concept,compute to analyze its static characteristics.The effects of such factors as inlet bulk temperature,power-type,diameter and height of the loops,coefficient of local resistance at inlet are also related as well. |
