MHD Mixed Convection Flow and Heat Transfer of a Dual Stratified Micropolar Fluid Over a Vertical Stretching/ Shrinking Sheet With Suction, Chemical Reaction and Heat Source

Abstract

The purpose of this study was to investigate the magnetohydrodynamic (MHD) mixed convection flow and heat transfer of a dual stratified micropolar fluid over a vertical permeable stretching/ shrinking sheet with chemical reaction and heat source. The governing nonlinear partial differential equations are reduced into a system of nonlinear ordinary differential equations using an appropriate similarity transformation. Then, the obtained ordinary differential equations are solved numerically using the boundary value problem solver (bvp4c) in MATLAB software. The numerical results are tabulated and plotted for the heat transfer characteristics, namely, the skin friction coefficient, the local Nusselt number, the local Sherwood number as well as the velocity, temperature and concentration profiles for some values of the governing parameters. The present numerical results also have been compared with the previous reported results for a particular case and the comparisons are found to be in an excellent agreement. The results indicate that the skin friction coefficient and the local Nusselt number increase with chemical reaction and heat source. The magnitude of the local Sherwood number increases with the increasing of chemical reaction parameter. However, the magnitude of the local Sherwood number decreases with heat source effect.

Unsteady MHD Stagnation Point Flow of Al2O3-Cu/H2O Hybrid Nanofluid Past a Convectively Heated Permeable Stretching/Shrinking Sheet with Suction/Injection

“…In another study, Dhanai et al, [44] examined a MHD boundary layer nanofluid flow with viscous dissipation passes through a power-law permeable sheet, where they found out the presence of dual solutions with respect various stretching/shrinking parameter. The study of slip, chemical reaction, and Joule heating effects on magnetohydrodynamic nanofluid and hybrid nanofluid has been conducted by Khan et al, [45,46], Ashgar and Ying [47] and Akaje and Olajuwon [48]. The examination on an unsteady MHD flow at the forward stagnation-point was first prompted by Katagiri [49], Pavlov [50] and Takhar et al, [51].…”

Thermal Properties of Wood Dust Fibre and Recycled Polypropylene (r-WoPPc) for Development of Thermoplastic Composites Filaments of Fused Deposition Modeling

“…Wood is thermally inefficient (and has a high heat-insulating capacity). As a consequence, light, dry woods are superior insulators to heavy, damp woods [2,3]. With many academics publishing their findings and reviews, interest in natural fibre composite FDM has significantly increased [4,5].…”

Numerical and Experimental Modelling of Small Hydropower Turbine

“…Large power plants placed on dams, including Haditha dam in Anbar province, have been affected by reduced production of generated energy due to the low water level within the Euphrates River, as well as thermal and gas power plants, which require high flows for the operation of cooling systems such as The Zweia station in Anbar province (This type of station (small-generation plants) which is the subject of our research is one of the most successful solutions that must be studied and developed in Iraq. There is a greater impetus towards the renewable energy sources to increase the global energy produced [3][4][5][6][7][8][9]. Hydropower was introduced to be an alternative solution, especially since 71% of the land is covered with water, this means that an inexpensive and environmentally friendly electrical energy can be generated, and this energy can expand rapidly [10].…”
