This study delves into the magnetohydrodynamic (MHD) flow of Casson-based nanofluids over a linear stretching sheet, accounting for multiple influencing factors. These findings offer significant real-time applications across a spectrum of fields, including energy generation, environmental engineering, and materials science. The acquired insights into Casson-based nanofluid behaviour within magnetohydrodynamic contexts can foster efficiency improvements, energy conservation, and enhanced overall system and process performance. Furthermore, the current study aims at Casson-based nanofluid's magnetohydrodynamic flow across a linear stretching sheet considering effects of thermal radiation, heat source/sink, and porosity. The governing equations are converted to ordinary differential equations by using similarity transformations. The Runge-Kutta-4 method, along with the shooting technique, is used to solve the reduced equations. The effects of dimensionless parameters, magnetic, Casson, thermophoresis, thermal radiation, and Brownian motion on velocity, thermal, and concentration profiles are considered in the study. As the magnetic and Casson parameters are increased, the findings indicate a reduction in the thickness of the momentum boundary layer. Moreover, the fluid temperature intensifies with the enhancement of thermophoresis and Brownian motion of particles. Finally, for various combinations of applied parameters, the values of skin friction coefficient, Nusselt number, and Sherwood number are obtained and are shown in the tables. The research is unique in a way that incorporates the impacts of heat source/sink and porosity as well as a more precise description of Casson nanofluid flow when compared to earlier findings. The novelty of the investigation lies in the implementation of a heat source/sink and porosity to obtain refined Casson nanofluid flow.

“…Nagamani et al [3] examined the effect of Casson fluid properties on the three key transport coefficients, namely exchange, convection, and dispersion coefficients, within a conduit (pipe/channel). Yashkun et al [4] investigated characteristics of stagnation boundary layer (BL) flow and heat transfer of Casson liquid past the stretched/shrunk surface. Study also considered the influence of a heat source and the injection effect.…”

The aim of current research is to assess heat transfer characteristics over a cylinder undergoing stretching or shrinking using Cason Nanofluid. Additionally, dual solutions stability has been analyzed. The governing equations for the two-phase model consist of partial differential equations (PDEs), which are subsequently transformed into ordinary differential equations (ODEs) through the application of similarity transformations. This transformed system is afterward resolved numerically utilizing solver bvp4c within MATLAB software. The numerical results of momentum, temperature, and concentration distribution are visible for both phases. The graph also shows the results of skin friction coefficient, heat transfer coefficient, and the Sherwood number. Furthermore, the validity of the current data is confirmed and shown to be in good agreement by comparing them to the existing literature. The variation of Casson nano fluid velocity, which is the variation of reduced skin friction coefficient ( 1/2) , increases as the Casson fluid parameter values increase. The temperature variation indicates that the local Nusselt number variation − ′(0) decreases as the curvature parameter values increase. The first solution is characterized by positive values of the smallest eigenvalues 1 > 0, suggesting stability. Conversely, the second solution is associated with negative values of the smallest eigenvalues 1 < 0, indicating instability. Keywords: Dual solutions; Stability analysis; Casson nanofluid; Heat transfer; Buongiorno's model.

Engine Oil is a widely used fluid in engineering problems, particularly to enhance the rate of heat transfer when these working fluids play a fundamental role. We consider engine oil as a base fluid and the suspension of different shaped (Spherical cylindrical and platelet) nanoparticles dispersed uniformly in the base fluid to enhance the working capability of engine oil. The spherical shape $${\text{CuO}}$$ CuO , platelet shape $${\text{Al}}_{2} {\text{O}}_{3}$$ Al 2 O 3 and cylindrical shape $${\text{TiO}}_{2}$$ TiO 2 nanoparticles are added in engine oil to constitute tri-hybrid nanofluid aiming at obtaining better thermal performance. Furthermore, we also analyze the Jeffery tri-hybrid nanofluid in a rotating frame over an infinite vertical plate. More precisely, the classical model of Jeffery tri-hybrid nanofluid is transformed into a time-fractional model by applying the newly developed constant proportional Caputo fractional derivatives. Sharp numerical results are obtained applying a Laplace transform steered approach. All the flow parameters are highlighted through graphs via MATHCAD. Furthermore, a comparative analysis between nanofluid, hybrid nanofluid and tri-hybrid nanofluid has been performed showing that tri-hybrid nanofluid has good thermal performance. The solutions of the constant proportional operator are discussed classically by taking fractional parameter α → 1. Moreover, some engineering quantities have been calculated and presented in tables. During the analysis we dispersing the mixture of nanoparticles in engine oil base fluid enhanced the heat transfer up-to18.72% which can efficiently improve the lubricity of the engine oil.
