“…Jalili et al 13 have extensively studied the radiation heat transfer in non-Newtonian fluids under various conditions. The nanofluid stream through the microchannel heat sink and its heat transfer phenomena were studied by Jalili et al 14 Investigations into the heat transfer process with chemical reactions and heat sources in non-Newtonian fluid flows were conducted by Jalili et al 15 The study of the Jeffrey fluid on MHD flow with stretching in porous sheets of a heat transfer system has been conducted by Jena et al 16 Another study conducted by Bouslimi et al 17 analyzed the effect of electromagnetic force and thermal radiation on the Williamson nanofluid on a stretching surface through a porous medium while considering heat generation/ absorption and Joule heating. Thermal radiation and a heat source are two factors that influence the flow and heat transfer of a non-compressible Jeffrey fluid that deviates from Newton's law of viscosity.…”

This study explores heat transfer in a system involving Jeffery fluid of MHD flow and a porous stretching sheet. The mathematical representation of this system is initially described using a partial differential equation (PDE), which is then converted into an ordinary differential equation (ODE) through numerical techniques such as Lie similarity and transformation methods, along with the shooting approach. The results indicate that altering the variables of Jeffery fluid, heat source, porosity on a stretching sheet, and the physical characteristics of the magnetic field within the system leads to an upward trend. Implementing this enhanced heat transfer system can yield benefits across various domains, including industrial machinery, mass data storage units, electronic device cooling, etc., thereby enhancing heating and cooling processes. Furthermore, the study also utilized Akbari-Ganji’s Method, a new semi-analytical method designed to solve nonlinear differential equations of heat and mass transfer. The results obtained from this method were compared with those from the finite element method for accuracy, efficiency, and simplicity. This research provides valuable insights into heat transfer dynamics in complex systems and offers potential applications in various industrial settings. It also contributes to developing more efficient and effective heat transfer techniques.

“…Jalili et al (14) examined heat transfer in a microchannel heat sink using Aluminum oxide-water nanofluid and considering a magnetic field. They applied the Koo-Kleinstreuer model for nanofluid properties, utilized an improved Darcy relationship for porous medium modeling, and employed the Collocation method to address nonlinearity in heat transfer relationships.…”

“…Obtaining solutions to these non-linear differential equations using the known analytical techniques is not possible. Hence, to obtain an approximate solution, numerical methods find scope in fluid mechanics [48][49][50][51][52][53][54]. FDM is one of the popular numerical methods in analysing many areas of science and technology.…”

The current paper studies the MHD and heat transfer characteristics of radiative upper-convected Maxwell fluid flow between two plates approaching or receding from each other with injection at the fixed lower porous plate. The governing momentum and energy equations are reduced into non-linear ordinary differential equations employing similarity transformations. With the help of the Homotopy Perturbation Method (HPM), an approximate analytic solution is obtained. This work aims to determine the effects of Reynolds number (R), Deborah number (De), Radiation parameter (Rd), Magnetic parameter (M), and Prandtl number (Pr) on the velocity and temperature profiles. It is observed that the Deborah number has a direct impact on the velocity profile when there is a squeezed flow. It is also observed that the magnetic parameter shows an indirect impact on the temporal distribution for both the upper plate moving away and towards the lower. The variations in the significant physical parameters on the coefficient of skin friction and heat transfer rates are also calculated. The results are then compared with the classical finite difference method and are in excellent agreement. It is found that larger the magnetic parameter, the dominance of viscous forces retards the velocity in the core region, and the increase in radiation parameter suppresses the heat transfer rates. This study is helpful in industrial applications, specifically in polymer processing.
