“…Melting heat transfer in steady boundary layer stagnation-point flow of a micropolar fluid towards a horizontal linearly stretching/shrinking sheet is investigated by Yacob et al [12] and later this work was extended to vertical stretching sheet by Rasekh et al [13]. Boundary layer flow and heat transfer of second grade fluid and Jeffrey fluid in a region of the stagnation point over a stretching surface with Thermal-diffusion (Dufour) and diffusion-thermo (Soret) effects combined with melting heat transfer are presented by Hayat et al [14], [15].…”

A comprehensive numerical study is conducted to investigate effect of melting on flow and heat transfer of incompressible viscous dusty fluid near two-dimensional stagnation-point flow over a stretching surface, in the presence of thermal radiation, non uniform heat source/sink and applied magnetic field. Using suitable transformations, the governing nonlinear partial differential equations are transformed in to a set of coupled nonlinear ordinary differential equations and then they are solved numerically. The influence of the various interesting parameters on the flow and heat transfer is analyzed and discussed through plotted graphs in detail. Comparison of the present results with existing results is shown and a good agreement is observed. We found that the velocity and temperature fields increase with an increase in the melting process of the stretching sheet.

Iron oxide nanoparticles have great importance in future biomedical applications because of their intrinsic properties, such as low toxicity, colloidal stability, and surface engineering capability. So, blood containing iron oxide nanoparticles are used in biomedical sciences as contrast agents following intravenous administration. The current problem deals with an analysis of the melting heat transfer of blood consisting iron nanoparticles in the existence of free convection. The principal equations of the problem are extremely nonlinear partial differential equations which transmute into a set of nonlinear ordinary differential equations by applying proper similarity transformations. The acquired similarity equalities are then solved numerically by Runge-Kutta Felhsberg 45th-order method. The results acquired are on the same level with past available results. Some noteworthy findings of the study are: the rate of heat transfer increases as the Casson parameter increases and also found that the temperature of the blood can be controlled by increasing or decreasing the Prandtl number. Hence, we conclude that flow and heat transfer of blood have significant clinical importance during the stages where the blood flow needs to be checked (surgery) and the heat transfer rate must be controlled (therapy).

Researcher tried to increase the thermal conductivity of regular fluids by suspending micro-or larger-sized solid particles in fluids. Since the thermal conductivity of solid is typically higher than that of liquids. Maxwell 1 initiated theoretical studies on heat transfer of fluid containing suspended solid particles. Later on numerous investigators expanded this original work. 2,3 Due to large size and high density, the solid particles settling out of suspension which induce additional flow resistance and possible erosion. Hence, fluids with dispersed coarsegrained particles have not yet been commercialized. Choi 4 from Argonne National Laboratory coined a term nanofluid which is combination of nano-sized particles (diameter < 100 nm) or fibers in the usual fluids. He confirmed that addition of nanofluids enhanced thermal conductivity by two times compared to normal fluid. Nanoparticles could control the processes of oil recovery according to Prodanovi et al. 5 Nanofluids are more stable compared to other fluids. It also has acceptable viscosity and better spreading, wetting, and dispersion properties on solid surface. 6,7 Kim et al 8,9 analyzed the crucial significance of nanofluids in the field of nuclear science. They confirmed that the nanofluids can improve the performance of any water-cooled nuclear system applications. Pressurized water reactor, primary coolant, standby safety systems, accelerator targets, plasma diverters, and so forth, are such possible applications. 10 T...

“…It is noteworthy to mention that although some sort of solution methodologies has been employed to investigate the melting heat transfer characteristics to date [15][16][17][18][19][20][21][22][23][24][25][26], the homotopy-based methodology, due to its optimization performed in MATHEMATICA package BVPh2.0 [27], can be developed as an efficient procedure compared to any other one [11,28]. It is found that this methodology does not suffer from long run-time and can provide high accuracy estimates.…”

In the present paper, we focus on the melting heat transfer characteristics of Casson fluid involving thermal radiation and viscous dissipation. To this end, the governing partial differential equations (PDEs) are transformed into the ordinary differential equations (ODEs) via the similarity variables. Besides establishing a homotopy-based methodology and its optimization performed in MATHEMATICA package BVPh2.0, the present findings are compared and validated by those available results in the literature. It can be shown that regardless of the variable fluid properties, this methodology predicts the heat transfer rate with and without melting effect at any Prandtl number. Furthermore, it is seen that the velocity distribution is significantly affected by the melting parameter.
