In manufacturing, especially in oil flow filtration, combustion systems, cooling turbines, and other areas, heat transfer performance through hybrid nanofluids (HNFs) is a key factor achieving dominance of the final product. The present study deals with movement fluid containing tri-hybrid nanoparticles on an excessively large stagnation point area smooth plate permeable medium. Additionally, leading partial differential equations proposed model are converted to ordinary (ODEs) by incorporating similarity variables, fourth-order Runge–Kutta method then used solve these. To find missing initial conditions first-order ODEs, shooting technique also used. Furthermore, consequences transmission rate form graphs tables explored.

In several situations, particularly, flow of viscoelastic nanofluids, the dynamic viscosity and thermal conductivity should be considered as variables due to their roles in various practical applications. Therefore, this article aims applying Cattaneo–Christov double-diffusion theory investigate three-dimensional (3D) forced second-grade nanofluids over a permeable stretching surface. The properties mixture are where is exponentially varied with temperature Brownian motion linearly dependent on concentration, respectively. included medium isotropic porous, both heat generation radiation impacts assumed. At surface, nanoparticles either active or passively controlled, convective boundary conditions for surface temperature. solution methodology based similarity transformations, numerical technique 4th-order Runge-Kutta method. major outcomes revealed that growth relaxation time δe parameter K causes gradually decreases features. Also, constant gives higher velocity features compared variable case. Furthermore, range coefficient ε1 an enhancement rate transfer by 5.26%.

Abstract Studying the flow of nanoparticles ( or ) in base fluid (blood plasma) over a permeable stretched sheet presence an induced magnetic field, which is primary aim research. The studied by applying temperature and velocity slip conditions. relevant partial differential equations are transformed into ordinary using suitable similarity transformations. Taylor wavelet operational matrix collocation method then employed to solve resulting (ODE), comparison Nusselt number local skin friction coefficient with those from previous research reveals good degree accuracy. findings study show that improves fluid's axial profile more than does when mixed blood plasma. Compared boundary constraints, no‐slip condition increases fluid.
