Mechanical Engineering

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution

Abstract

The present paper describes a Petrov-Galerkin based Least Squares approach for formulating the transient flow/thermal behavior due to solodification processes. Both single and multiple phase change effects are considered in this study. And, emphasis is placed upon comparisons of the present developments with available experimental results and or results published in the literature. An adaptive time stepping strategy is employed for the trapezoidal family of methods. Applications to practical situations where previous studies have been done are presented. The overall developments agree well and validations are presented in this paper.
