The magnetohydrodynamic flow of an Oldroyd-B fluid across a vertical stretching sheet through a porous medium is investigated. Using a similarity transformation, the boundary layer equations for momentum, thermal energy, and concentration can be simplified into a set of linked ordinary differential equations. The successive linearization method is then used to numerically solve the system of ordinary differential equations. Graphical and tabular representations of the physical parameter effects on velocity, temperature, concentration profiles, the local skin friction coefficient, and heat and mass transfer rates are provided. Deborah's number in terms of relaxation time has been reported to resist and slow down the motion of fluid particles at different time instants in terms of relaxation time. By raising Deborah's numbers in terms of relaxation time, the temperature profile rises. Additionally, excellent agreement was found after the current results were examined and contrasted with the published results.

“…Recently, there has been an increasing number of studies focusing on the Homann and Hiemenz flow problems, as discussed in Refs. [5] and [6]. Sumio Iijima [7] revolutionized the concept of carbon nanotubes through an experiment in which he took two graphite rods as electrodes and applied current across them, resulting in a spark arch between them and clouds of carbon gas and vaporizing the tip of the anode rod.…”

Carbon nanotubes have garnered considerable interest from academia and industry due to their unique properties and potential applications. This study examines fluid flow induced by a plate moving at a constant velocity towards/receding from normal stagnation point flow. The plate's surface is immersed with ethylene glycol and two types of carbon nanotubes: single‐walled and multi‐walled. The Reynolds number, proportional to the plate's velocity, governs the flow. Thermal transport analysis includes Ohmic heating, heat source/sink effects for constant wall temperature and prescribed surface temperature, and entropy generation analysis. Similarity ansatz is used to obtain non‐dimensional ordinary differential equations, and numerical and asymptotic solutions are computed using MATLAB's bvp4c routine (finite difference‐based approach). By varying the relevant parameters, the study interprets the behavior of entropy generation, Bejan number, skin frictions, Nusselt number, flow, and energy profiles. The numerical solutions are observed to match their asymptotic behaviors within an intermediate range of small and large Reynolds numbers for the wall stress parameter. The magnetic parameter produces a resistive force that reduces fluid flow but enhances the system's energy. Moreover, understanding the flow and heat transfer characteristics of CNT‐based nanofluids induced by a moving plate can provide insights into the design and optimization of thermal systems, including efficient heat exchangers used in power generation, chemical, and petrochemical industries.

IntroductionCurrent advancements in nanotechnology have made it much easier to create nanoparticles or nanostructures with higher thermophysical properties than their bulk counterparts utilizing nuclear or molecular processes. Salah et al (2023) developed Nano fluids by dispersing nanoparticles in a base fluid such as water, oil, or ethylene glycol, to name a few. The study of Nano fluids has witnesses a rise in research activities over the years.

In this article, the implications of viscous dissipation on buoyancy-induced heat and mass transfer of a nanofluid flow along a semi-infinite flat plate in an oscillating system is performed, taking into account the impacts of magnetohydrodynamics (MHD), chemical reaction, porous medium and heat sink. The consequences of various flow parameters on the velocity, temperature, and concentration distribution of the nanofluid, as well as the skin friction coefficient, Nusselt number, and Sherwood number has been solved semi-analytically. The basic governing equations have been determined by employing appropriate transformations techniques which result in high nonlinear coupled differential equations with physical conditions. Different types of nanoparticles are considered, and the salient features of all the embedded parameters on velocities, temperature and concentration ﬁelds have been displayed graphically and illustrated. It is concluded from the computational analysis that application of viscous dissipative parameter improves the temperature distributions, which consequently speed up the fluid velocity. This model has practical applications in the fields of biomedicine and resonance imaging. In addition, graphical comparison between Narayana and Venkateswarlu (2016) with the present work demonstrate an excellent relationship, thereby authenticating the precision and accuracy of this present work.
