Thermofluid of Maxwellian type past a porous stretching cylinder with heat generation and chemical reaction

This article evaluated the effects of heat generation and the chemical reaction of Maxwell fluid over a porous stretching cylinder. Partial differential equations are framed using the mentioned parameters. The partial differential equations for momentum, heat, and mass are changed using similarity transformations into highly nonlinear ordinary differential equations. These equations are answered numerically via the Runge-Kutta with the shotting scheme of the 4th order in MATLAB with the help of inbuilt software bvp4c. Results are offered graphically and in tabular format for essential parameters over a velocity, temperature, concentration, skin friction coefficient, Sherwood number, and Nusselt number. We checked our coding against an existing article and obtained a good match. The essential findings of this research are that velocity decreases as the permeability parameter rises. It has been observed that a viscoelastic fluid parameter induces a decreasing velocity profile. Due to the Maxwell fluid, porosity, heat generation, and chemical reaction parameters, the thermal profile has been improved. These results have several manufacturing applications, including metal turning, the fabrication of glass filaments, the formation of elastic sheets, wire drawing, the ejection of polymer sheets by oil companies, and the synthesis of polymers

Heat transfer in three dimensional micropolar based nanofluid with electromagnetic waves in the presence of eukaryotic microbes

Microorganism motility holds significant importance in the realm of biomedical research. It contributes to the investigation of bacterial infections, microbial pathogenesis, and the formulation of strategies for combating antimicrobial resistance. Motile microorganisms embody a multifaceted and dynamic facet of microbial existence, exerting influence on ecosystems, human health, and advancements in technology. The significance of the current investigations is to develop a steady 3D computational model for the magnetic field hydrodynamics micropolar nanofluid along with the Buongiorno model which incorporates Brownian motion and thermophoretic diffusion effects to describe the heat transfer enhancement of micropolar nanofluid. The influence of thermal radiation on convective boundary conditions is also considered here. Similarity transformations are employed to convert an equation of motion into an ordinary differential equation. The final shape of ODEs is solved numerically with the aid of MATLAB software. Graphical results against convergence parameters like the influence of magnetic parameter, velocity ratio parameter, Prandtl number, micropolar parameter, porosity parameter thermophoretic number, Brownian motion, bio-convective Schmidt number, Peclet number thermal radiation parameter is demonstrated on velocity, temperature, concentration, motile and angular profiles. The default values of physical parameter used our analysis are: 0.2≤M≤0.5, 0.2≤λ≤0.6, 0.2≤K≤0.5, 0.0≤K1≤2.0, 1.0≤Sb≤1.4, 0.1≤σ≤0.9 0.1≤Nr≤0.9, 0.3≤Nt≤1.8, 1.5≤A≤3.5, 0.0≤B≤2.0; 0.0≤Nb≤2.0, 0.5≤γ≤2.5, 0.0≤S≤0.8, 1.0≤Sc≤1.8, 0.0≤D≤2.0, 0.1≤Pe≤0.5.The novelty of the present model is validated with the previously published data and found an excellent agreement. Our obtained results signifies that a rise in the mass and temperature convective parameter causes the velocity profile to grow, but a rise in the porosity and magnetic parameter causes it to decrease. The temperature profile increases with a rise in, thermophoretic parameter, and magnetic parameter, whereas it decreases with a rise in temperature exponent and Prandtl number. This research brings esteemed insights the micropolar nanofluids make them attractive options for a variety of uses in a range of sectors, such as manufacturing, energy, electronics, and healthcare
