Darcy-Forchheimer higher-order slip flow of Eyring-Powell nanofluid with nonlinear thermal radiation and bioconvection phenomenon

Muhammad Mubashir Bhatti et al.

Summary: In this study, the application of slip phenomenon in a non-Newtonian Eyring-Powell nanofluid model confined by a stretching sheet was investigated. Numerical simulations showed that the slip parameter controls the velocity and improves the heat and mass transportation phenomenon. The concentration of nanoparticles increases with inertial forces and activation energy. Moreover, bioconvection decreases the microorganism profile, while higher values of the slip parameter result in an increasing trend.

Dynamics of melting heat transfer in thermally developed and chemically reactive flow of Eyring- Powell liquid through a curved channel

M. Naveed et al.

Summary: This article focuses on the consequences of melting heat transfer on the chemically reactive flow of Eyring-Powell liquid flow in a semi-permeable curved channel in the presence of an applied magnetic field. The effects of homogeneous and heterogeneous chemical reactions are considered in the concentration equation, and the characteristics of heat transport phenomena are examined with the application of thermal radiation. Nonlinear ordinary differential equations are obtained through the adoption of a curvilinear coordinates system and appropriate similarity conversions. Numerical simulations are used to estimate the determined velocity and transport equations using the shooting procedure. The influence of pertinent factors on the flow equations, surface drag force, and rate of heat transport is thoroughly discussed through graphs and tables.

Heat transfer analysis in a curvilinear flow of hybrid nanoliquid across a curved oscillatory stretched surface with nonlinear thermal radiation

Muhammad Imran et al.

Summary: The study aims to investigate the effects of nonlinear thermal radiation on the flow of hydromagnetic hybrid nanoliquid over an oscillating stretched curved surface. The influence of velocity and thermal slip conditions is also considered. A curvilinear coordinate scheme is used to formulate the mathematical model of the flow, resulting in nonlinear partial differential equations. The formulated flow equations are analytically solved using the Homotopy analysis technique (HAM) to obtain convergent series solutions. The effects of various flow parameters, such as hybrid nanoparticles parameter, magnetic parameter, non-dimensional velocity slip parameter, dimensionless radius of curvature, dimensionless thermal slip parameter, Prandtl number, and dimensionless temperature parameter, on flow, pressure, surface drag force, temperature, and local Nusselt number are comprehensively investigated through graphs and tables.

Heat transfer analysis in hydromagnetic flow of couple stress fluid in presence of homogeneous and heterogeneous chemical reactions over a porous oscillatory stretchable sheet

Muhammad Naveed et al.

Summary: The objective of this theoretical study is to investigate the flow, mass, and heat transfer in a time-dependent couple stress fluid over a permeable stretching oscillatory surface, considering the effect of an applied magnetic field. The energy equation is modeled with thermal radiation and heat generation, while the concentration equation accounts for homogeneous and heterogeneous chemical reactions. Similarity transformations are used to obtain analytical solutions to the flow equations, and the effects of various parameters on the flow, concentration, and temperature distributions are discussed in detail using tables and graphs. It is observed that the amplitude of velocity and skin friction coefficient decrease with the couple stress parameter but increase with the magneto-porosity parameter.
