碩士 === 國立交通大學 === 應用數學系所 === 98 === In this study, the simulation of drop deformation in incompressible flow was executed by developing an immersed boundary method in the axisym metric cylindrical coordinates. The viscosity difference between two sides of drop interface was particularly considered in this paper. We implemented a semi-implicit second-order projection scheme to solve Navier-Stokes equations. Various viscosity between two sides of drop were tested on simulation, as well as the effect of the surfactant on drop, which affect the surface tension. In addition, the distribution of marker positions were stabilized by imposing the artificial velocity and compared to the original manner without imposition of artificial velocity.
