The convective three-dimensional magnetohydrodynamic (MHD) boundary layer transport of Casson liquid by an unsteady stretchable sheet set in a permeable medium with variable thermal conductivity is researched. Conservation laws of the mass, the momentum and the energy are changed into ordinary differential equations, which are numerically dealt with fourth order Runge-Kutta integration scheme in relationship with shooting procedure. The dimensionless velocity, temperature, skin friction coefficient and the local Nusselt number inside the boundary layer are processed and examined through graphs and tables for various parameters that portray the flow. The numerical outcomes got for the specific case are sensibly in great concurrence with the existing results.

“…Increasing the nanoparticle volume fraction with the suspensions of SWCNH and diamond nanoparticles enhances the temperature over the wedge, plate and stagnation point. A theoretical study on the flow of Casson nanofluid past a linear stretching sheet in a non-Darcian porous medium, under the influence of an inclined magnetic field, was performed by Trivedi and Ansari [4]. Heat transfer characteristics along with Joule and viscous dissipation were analyzed by considering the effect of nonuniform heat source/sink and it was found that the inclination angle parameter increases the thickness of the thermal boundary layer.…”

Over the past few decades, several researchers have produced a variety of nanofluids that are used as heat transfer fluids in many engineering and technological processes. A nanofluid is a kind of heat transfer fluid, containing nanoparticles (1-100 nm) that are uniformly and stably distributed in a base fluid. Nanoparticles can be metallic/intermetallic compounds, such as Ag, Cu, Ni, Au, Fe, and ceramic compounds such as oxides, sulfides and carbides. Liquids such as water, ethylene glycol, a mixture of water and ethylene glycol, diethylene glycol, polyethylene glycol, engine oil, vegetable oil, paraffin, coconut oil, gear oil, kerosene, and pump oil are used as base fluids. A wide range of applications for nanofluids in different areas have been reported in the literature. These include biomedical applications, lubrication, surface coating, petroleum processing, environmental remediation, and cooling systems for electronics.

“…While addressing the application of CCT to the study of the Casson fluid flow problem, several notable research efforts stand out. Trivedi et al 34 used quasilinearization at Chebyshev collocation points to obtain the solution to the unsteady flow of Casson fluid with nanoparticles. In a comprehensive analysis of laminar flow within Casson fluids, Kotha et al 35 employed collocation methods to discretize the differential equations, focusing on a detailed thermal analysis.…”

This paper presents exact, analytical, and numerical solutions to the two‐dimensional Casson fluid boundary layer flow over a moving wedge with varying wall temperature. The boundary layer flow of the Casson fluid with varying wall temperature is governed by a system of partial differential equations called Prandtl boundary layer equations modified by Casson fluid. By applying similarity transformations the governing system of partial differential equations is reduced to a system of nonlinear ordinary differential equations called as the Falkner–Skan equation modified by Casson fluid flow with heat transfer (C‐FSEHT). In the beginning, an exact solution of the C‐FSEHT is obtained for the particular values of physical parameters (i.e., , , , see nomenclature) in terms of two standard functions, namely error function and exponential function. Thus, obtained exact solution is then modified to obtain the analytical solution of C‐FSEHT for general values of physical parameters, in terms of power series. The analysis of the asymptotic behavior of the problem, when the wedge velocity is very large (), is performed using the Dirichlet series. A comparative analysis is performed using the Chebyshev collocation technique (CCT) to validate the obtained results in all the scenarios. The effect of governing parameters, which are the Casson parameter , Hartree pressure gradient parameter , moving wedge parameter , Prandtl number , and wedge temperature parameter on the skin friction coefficient, temperature coefficient, velocity profiles, and temperature profiles is discussed in detail. Multiple solutions are found analytically for fixed values of governing parameters. The fact that an increase in the value of the Casson parameter () reduces the thickness of both velocity and temperature boundary layers, is also validated during the study.
