โœฆ Synopsis

A numerical method which employs moving grid has been presented for computing multiple moving boundaries. Numerical solution has been obtained for a solidification problem in which freezing takes place over a temperature range. It has been shown that implicit boundary conditions at the moving boundaries can be tackled by considering an appropriate explicit boundary condition. Two models have been considered for the solid fraction in the mushy region and the validity of these models has been discussed in the light of integral heat balance.

A boundary element formulation for the solution of multiple moving boundary problems is presented and tested herein. A heat transfer problem involving heating of solid, melting of solid, and partial vaporisation of liquid is considered. Numerical results show that the boundary element method is more

The generalized Riemann problem (GRP) scheme for the hydrodynamic conservation laws is extended to a two-dimensional moving boundary tracking (MBT) configuration, aimed at treating time-dependent compressible flows with moving (impermeable) boundary surfaces. A Strang-type operator splitting is empl
