| 内容記述 | Numerical simulation of cavitating flow was performed to investigate the effect of different inlet conditions for turbopump inducers with three blades with a backward sweep and different inlet blade angle. The computation was carried out by solving the Reynolds averaged Navier-Srokes equations with a homogenous cavitation model and k-ω turbulence model. Numerical results concerning inducer characteristics and performance curves were compared with experimental results at difference flow coefficients and cavitation numbers. The occurrence of avitation and its spatial distribution in each inducer were also investigated. As the result, at the inlet tip blade angle decreases, the occurrence of cavitation decreases in the cavitation regime, resulting in increasing the cavitation performance. Also, it was found that the present computation simulated well the complicate cavitating flow in inducer and gave a good estimation of inducer characteristics. Detailed observation and development of cavitation with respect to the cavitation number as well as the inlet blade angle are provided and discussed. | |||||
