This thesis presents development of mathematical models for liquid-solid phase change phenomena using Lagrangian description with continuous and differentiable smooth interface (transition region) between the solid and the liquid phases in which specific heat, thermal conductivity, and latent heat of fusion are a function of temperature. The width of the interface region can be as small or as large as desired in specific applications. The mathematical models presented in the thesis assume homogeneous and isotropic medium, zero velocity field (no flow) with free boundaries i.e. stress free domain. With these assumptions the mathematical model reduces to the first law of thermodynamics i.e. energy equation. The mathematical models presented h...
