Thermoelastic interactions in a rotational medium having variable thermal conductivity and diffusivity with gravitational effect

Abstract

ABSTRACT This research work is related with the investigation of thermodynamical interactions for a rotational thermodiffusive medium including gravitational effect. To differentiate it from existing works, thermal conductivity and mass diffusivity are considered as variables. The governing equations are formulated under Green–Lindsay (G-L) theory by using Kirchhoff's transformation. Thermal and chemical shocks of constant intensity are imposed on the boundary surface. By using normal mode technique, solutions for the variables considered such as displacement, stress, temperature and chemical potential are achieved. Numerical results are computed for copper material. The impacts of variable thermal conductivity, variable diffusivity, rotation and gravity on different physical fields in the medium are depicted through various figures.
