This simulator consists of turbo pump system simulator and tank system simulator. In this paper, the tank system simulator based on CIP-LSM, which computes free surface behavior, temperature and pressure in rocket propellant tank, is presented. Also, the computed results of 2D sloshing and broken dam problems are presented to assess the accuracy of the solver for problems with strong deformation of the fluid. The results were in good agreement with other published data and experiments. As a result, it was clear that CIP-LSM is an effective method for predicting strong deformation of free surface flows., 資料番号: AA0049056002, レポート番号: JAXA-SP-05-010}, title = {ロケットエンジン供給系流れの数値解析}, year = {2006} }
