An efficient computational technique to solve the moving boundary problems in the axisymmetric geometries (Q1309688)

A key feature of the present work was that the numerical formulation of the pseudo-velocities arising from the boundary immobilization was not derived, as in the conventional approaches, directly from the mathematical expressions but based on the physical meanings pertaining to them. Therefore, the numerical values of the pseudo-velocities and the time-dependent volume elements were determined algebraically instead of solving the field equation for the pseudo-velocities.
