| Summary: | 碩士 === 淡江大學 === 航空太空工程學系碩士班 === 104 === This paper first applies pre-conditioning incompressible multi-fluid flow model based on sharp interface technique to simulate the bubble rising flow problems. Here, the preconditioning matrix modified from Chorin’s artificial compressibility concept is used to make the incompressible multi-fluid Navier-Stokes equations to be hyperbolic. Therefore, a simple convection-pressure flux-splitting method with the THINC formulation for volume fraction function compressed reconstruction is used to maintain the preservation of sharp interface evolutions of bubble rising flow simulation. The revolution of a rising bubble at different Bond number and Archimedes number is shown and discussed.
