内容記述 | In cryogenic fluid, such as rocket propellants, thermal effect has to be properly treated, which is usually neglected in common fluids. In the present study, a cavitating flow solver, which is based on bubble two-phase flow model including energy equation, was constructed and flow calculation was carried out around 2D NACA0015 airfoil. Comparison between water and liquid nitrogen reveals that cavitating pattern between these two fluids are completely different and this difference was raised from thermal effect of cryogenic fluid. The effect of numerical dissipation was also discussed to reveal that excess numerical dissipation affected the cavitation very much, consequently, cavitation performance became completely different from that due to the higher-order calculation. | |||||
