Melting heat phenomenon in thermally stratified fluid reservoirs (Powell-Eyring fluid) with joule heating

Abstract

The currant study focuses on the characteristics of melting heat phenomenon in the Powell-Eyring fluid flow deformed by the linearly stretchable sheet in the vicinity of stagnation point. Quadratic thermal stratification, thermal radiation, viscous dissipation and Joule heating are implemented to disclose the heat transport properties. Magnetic field is implemented to the fluid with an angle α. Mass diffusion is scrutinized through quadratic solutal stratification and constructive/ destructive chemical reactions. A system of dimensionless governing equations are achieved through appropriate transformations. Physical behaviors of temperature, velocity and concentration fields are elaborated through graphs. Skin friction, entropy generation, rates of mass and heat transfer are disclosed through graphs corresponding to pertinent parameters. Decrease occurs in temperature field for dominant melting and thermal stratification phenomenon. Entropy has inverse behavior in case of dominant thermal stratification while similar behavior of melting case. The interesting behavior in melting heat transfer phenomena is the increase of temperature as we raise the Prandtl number. Also, it is worth mentioning that the velocity outline accelerated and temperature profile decelerated with the enhancement of melting factor.
