要約

Numerical methodology of sharp-interface level-set-method (SI-LSM) on a non-uniform and staggered grid for two-phase flows with phase change is presented. Verification as well as performance study of the SI-LSM (on a non-uniform as compared to uniform grid) are also presented. For the implementation of the difference in the discretization method of the various conservation laws on a non-uniform grid, necessary changes due to an offset in the grid points for flow variables are illustrated in the present work. Implementation of the FDM based ENO scheme on a highly stretched nonuniform grid is presented; derived here using Lagrangian interpolating polynomial. Fluid-flow and interface solvers on the non-uniform grid are verified with published results on the breakup of a liquid jet problem. Energy-equation and interface solvers (on a non-uniform grid) are verified with an analytical solution on simultaneous heat and mass transfer induced Stefan flow. Finally, the fluid flow, energy-equation, and species-equation solvers are coupled to simulate flow involving both heat and mass-transfer induced phase change. For two-phase flow with phase change, performance study (on a non-uniform grid) is presented on a problem involving evaporation of a falling droplet in air.
