A Stefan problem with moving phase change material, variable thermal conductivity and periodic boundary condition

作者：

Highlights：

• FDM is used to a Stefan problem with size-dependent thermal conductivity.

• Consistency, stability and convergence of the numerical scheme are deliberated.

• Size-dependent thermal conductivity reduces the melting process.

• Moving PCM enhances the speed of melting front.
