生成項および仮想質量力が二流体モデルの数学的性質に及ぼす影響 : 第2報, 数学的性質の評価

摘要: As is by now well known, partial differential equations based on a one dimensional, one-pressure two fluid model are mathematically ill-posed as an initial-value problem. Up to the present, however, eigenvalue analysis of has been conducted only for simplified two-fluid without any source terms, since necessary condition well-posedhess can be derived from terms only. Consequently, effects have not systematically investigated. In previous report, we proposed method examine mathematical nature complete including ; gravity were evaluated using this method. result, it was confirmed due terms. present study, interfacial drag force and wall friction examined same The virtual mass also evaluated, its influence clarified in spite fact that affect numerical stability.
