“…Kamal et al (2019) concentrated on the conjugate study of flow and heat transfer considering two physical effects such as g-jitter and thermal radiation on a threedimensional stagnation point region. Recently, Nayan et al (2022) used hybrid nanofluids in their study to increase heat transfer performance.…”

This paper deals with the numerical solutions for the aligned MHD free convection laminar boundary layer flow over a moving inclined plate for two magnetic nanofluids, namely Fe3O4-water and Fe3O4-kerosene. It is assumed that the left surface of the plate is in contact with a hot fluid while the cold fluid is on the right surface. The mathematical model has been constructed and based on the Tiwari-Das model, appropriate similarity transformations are used to convert the governing partial differential equations into nonlinear ordinary differential equations and solved numerically using the Keller-Box method. Numerical results for the skin friction coefficient and local Nusselt number were presented whilst the velocity and temperature profiles were illustrated graphically and analyzed. It is found that the velocity increases and temperature decrease with an increase of aligned magnetic field angle parameter, magnetic strength parameter, and Grashof number while the velocity decreases and temperature increase when inclined plate angle parameter and volume fractions of nanoparticles increase. For the convective parameter, both velocity and temperature profile increase when the Biot number increase. Comparisons with previously published studies are performed and excellent agreement is obtained.

“…The meshing size have been set as [Δ𝑦, Δ𝑥, Δ𝑡] = [0.05, 0.05, 0.01], with the shortness ignorance 𝑂(Δ𝑦 2 + Δ𝑡 2 + Δ𝑥) when Δ𝑦, Δ𝑥 and Δ𝑡 approach the value of null. Moreover, [𝑥 𝑚𝑎𝑥 , 𝑦 𝑚𝑎𝑥 ] = [1,10] is the integral area. It is feasible to deduce from the computations, predictions, and calculations made before that a complex and systematic plan of action reveals that a solution may appear and function in agreement as explained in previous studies [35][36][37].…”

“…Investigation of the effects of this buoyancy force together with MHD is essential in various fields. Previously, Nayan et al, [1] investigated aligned MHD flow with a constant wall temperature. They discovered that when the interaction of the magnetic parameter and the angle of aligned magnetic field enhances, the velocity profiles increase, and the temperature profiles decrease.…”

The implications of suspended particles on MHD flow in a viscous fluid over a non-isothermal vertical cone with dissipation effect was investigated in this recent research. To maximise process efficiency and avoid equipment failure, it is important to thoroughly investigate the complex and dynamic behaviours that might result from the interaction between the fluid and the dust particles inside the cone. The Crank-Nicolson method will be used in the study to analyse the mathematical model quantitatively. MATLAB software was used to compute the discretization equations and depict the numerical outcomes. The velocity distribution, temperature distribution, skin friction and Nusselt number affected by Prandtl number, magnetic, mass concentration of particle phase, viscous dissipation and fluid-particle interaction for particle and fluid phases are presented graphically as well as in a table and are thoroughly analysed. The outcome indicated that the fluid and dust phase velocity decreases when magnetic, mass concentration of particle phase and fluid-particle interaction parameters are escalated while viscous dissipation parameter shows an opposite behaviour. Moreover, the temperature and velocity profiles for the fluid phase are consistently greater than those for the dust phase in every result that was examined.

“…The improvement in the performance is seen around 1.2% for 5% addition TiO 2 particles in base fluid. Asmahani Nayan et al, [25] conducted numerical analysis of MHD flow of hybrid nanofluid over a vertical plate in porous medium. A comparative study from the results obtained shows that Nusselt number of CuO -water is less than Ag -CuO / water.…”

The study investigates the flow characteristics of spherical shaped TiO2 –Ag hybrid nanofluid with water as a base fluid passing through a wet porous rectangular moving fin with a focus on understanding the effects of nanoparticle concentration on the heat transfer rate. The fin under consideration are subjected to boundary conditions, insulated and convective tips. Hybrid nanofluid that combine nanoparticles with conventional base fluids have potentially enhanced thermal conductivity and heat transfer properties in engineering applications. The energy balance equation containing the parameters that effect the flow of heat transfer rate is non- dimensionalized and solved numerically using 3-stage Lobatto - IIIa formula with appropriate boundary conditions. The simulation result shows the impact of different parameters on the flow and heat transfer properties of the hybrid nanofluid obtained by mixing spherical shaped TiO2 –Ag hybrid nanoparticles with water as base fluid. It is observed that the fin shows significant heat transfer rate in a convective tip relative to an insulated tip. The findings contribute to the understanding of hybrid nanofluid flow and its potential application in the design and optimization of thermal management system. It also facilitates the ground work for research in the field of nano fluid based cooling system. The observation from the graphical illustration shows that the rise in the thermal conductivity of the base fluid by 23% increases the conduction heat transfer as well as the temperature distribution by 10%. The natural convection and radiation are the key parameters that determines the heat transfer rate from the surface to the surrounding. In our investigation, enhancing the Nc,Nr parameters by 50% and 25%, the temperature distribution profile is reduced by about 13% and 6% respectively. The increase in the Pe number by 100% results in a rise in the temperature distribution by 8%.
