摘要: 
An analysis is performed to investigate the mass transfer on the melting phenomenon from a vertical plate in a liquidsaturated
porous medium. The governing partial differential equations are reduced to nonlinear ordinary differential
equations by using appropriate dimensionless variables. The final resulting boundary value problem is then solved by
means of the Runge-Kutta-Gill method associated with Newton’s iteration. As shown in the results, the melting process
is highly affected by mass transfer effect. With increasing the strength of the buoyancy ratio, the melting effect may be
inhibited because the heat flux is removed by stronger convection. The Lewis number has a more notable effect on the
local mass transfer rate than it does on the local heat transfer rate at the solid-liquid interface. Additionally, the Lewis
number may affect the melting phenomenon when the mass transfer is considered in the system. The little change for
the melting effect can make a great influence on the local mass transfer rate, which is significant when the system is
dominated by mass transfer for a larger Le.
