Abstract
The melting procedure with a direct contact of phase change material is taken into account to consider the porous medium in the presence of a uniform and transverse magnetic field. A permeable rotating disk is taken as a heater in the melting progression of solid phase change material. The three-dimensional melting layer takes place due to the accruing of the temperature difference among the porous disk and solid material. Movement is subject to the effect of pressure loading (counting the weight of solid), direct relation with solid and rotation due to centrifugal force. The removal of melting is controlled due to the joint exertions of the porous media, wall permeability and resistive force generated due to the applied magnetic field. The motion of the melting layer is assumed unsteady and governed the nonlinear similarity equations. Furthermore, magnetic field, porosity, external load and wall suction enhance melting and heat transfer rates at the thin melts film thickness. The melting rate, momentum and thermal boundary layers are estimated under the impact of Stefan number, magnetic field, porosity parameter and unsteadiness parameter. The Eckert number enhances the thermal boundary layer, and consequently the larger amount of melting received. The governing PDEs is highly nonlinear; thus for the solution we use analytical method of HAM and BVPh 2.0 package. The important outputs of the thickness of the thin layer during melting process in the presence and absence of wall suction are mainly focused.
Highlights
Most of the useful products are produced due to the melting of solid materials, and these melts are used in many engineering, biological and industrial applications
Lacroix[7] had examined the melting phenomena inside a capsule in contact with phase change material for melting. He noticed that the close contact melting obtained due to the heat surface of the solid phase change material is more effective than the heat shifted by convection, which normally exists in much thicker layers of liquefied substances
The solution of the nonlinear problem has been tackled through the BVPh 2.0 package
Summary
Most of the useful products are produced due to the melting of solid materials, and these melts are used in many engineering, biological and industrial applications. To control the melting on a rotating permeable disk which was considered as a heater, a valid quantity of suction was incorporated without allowing the increase in melt layer film thickness, which is mentioned in the current study.
