Exploration of dissipative heat energy in conjunction with various thermophysical properties of nanofluids: Water and ethylene glycol base fluids

Abstract

The current research work intended to an electrically conducting nanofluid flow phenomena using oxide nanoparticles subjected to submerged water as well as ethylene glycol base fluids. The flow past a radically stretching sheet is surrounded by a permeable medium. The inclusion of thermophysical properties of viscosity and conductivity enhances the heat transfer phenomenon. The dissipative heat due to the interaction of the magnetic force is incorporated in the energy equation to increase its efficiency. The formulated nonlinear governing equations are re-constructed by imposing suitable similarity transformations. The unique feature of this investigation is that the problem validation is attained by using an approximation analysis procedure like the Differential Transform Method and also obtained with the help of the Pade-Approximant technique. Further, the computation is made using the numerical technique. However, the important outcomes are; that the particle concentration presents its key role in the smooth enhancement of the velocity distribution whereas the resistivity offered by the inclusion of the magnetic and porosity retards it significantly.
