Significance of Darcy Forchheimer Effect and MHD Stagnation Characteristics of Casson Ternary Nanofluid Flow Over Porous Curved Stretching Surface

Objective: To model and scrutinize the Darcy-Forchheimer flow with MHD stagnation characteristics of Casson ternary nanofluid flow over porous curved stretching surface. Methods: Flow of porous space is characterized by Darcy Forchheimer relation. Nanoparticles such as 𝑇 𝑖𝑂2, MgO, and 𝐶𝑜𝐹 𝑒2𝑂4 with a base fluid are investigated. The partial differential equations are reduced to ordinary differential equations through the application of a suitable similarity transformation. Numerical results for the problem are generated using the BVP4C method. The investigating the influence of different value of magnetic field parameter M, porosity parameter A, Prandtl number Pr, Darcy Forchheimer Fr, Casson fluid parameter 𝛽, nanoparticles volume fraction 𝜙1 are determined numerically and presented through graphs. The effect of various parameters on Skin friction and Nusselt number are compared and analyzed. Findings: Graphical representations of velocity and temperature distributions reveal the influence of emerging flow variables. In temperature profile 𝜃(𝜂) boosts for higher values of 𝜙1, M, Fr, 𝛽. Velocity distributions 𝑓′(𝜂) rises for increasing values of 𝜙1 and while declines for Fr, M and 𝛽. In case of skin friction 𝐶𝑓𝑠 (𝑅𝑒𝑠) 1 2 shows decreasing behavior for S and 𝜆 whereas Nusselt number 𝑁𝑢𝑠 (𝑅𝑒𝑠) −1 2 increases behavior for S and 𝜆.Novelty: Given the widespread relevance and possibilities associated with non-Newtonian fluids, our study examines the present fluid problem by employing the Casson ternary nanofluid flow over porous curved stretching surface, taking into account the Darcy-Forchheimer term in momentum equation. The (MgO),(𝑇 𝑖𝑂2) ,(𝐶𝑜𝐹 𝑒2𝑂4) study examines the flow behavior of ternary nanofluid past a curved stretching surface is considered in the present study. While no one has considered these nanofluids for the same model. Keywords: Curved surface; Stagnation point flow; Ternary Nanofluids; Darcy-Forchheimer flow; MHD; Casson fluid
