| Outline of Final Research Achievements |
We developed numerical methods to solve a flow around moving objects in two-phase flowfield and analyze coupled phenomena of thermos-fluid problems. The two-phase flow simulation was conducted by conservative level set method for interface between gas and liquid. In addition, practical engineering applications like engine oil lubrication around piston rings and water film analysis around a tire were dealt with accurate finite difference scheme and level set method to express wall boundaries. Furthermore, thermos-fluid couple simulation for a heat pipe was carried out by conjugate heat transfer model for the interface between fluid and object and sharp interface treatment between liquid and gas.
