Mathematical analysis and stability of thermally magnetized ternary hybrid nanofluid over porous moving wedge with suction/injection and entropy generation

Present study investigates the ternary hybrid nanofluid to analyze thermally magnetized flow over a moving wedge with wall permeability and convective boundary conditions. Using stability analysis and suction and injection give the novel contributions to the study. Water host fluid containing titania, silver, and graphene nanoparticles is used. A self-similarity approach is applied to convert the Partial Differential Equations into dimensionless Ordinary Differential Equations. Numerical solution has been obtained through bvp4c method. Duality has been observed due to suction and injection. From the stability analysis it is perceived that first solution is stable while the second solution is unstable. The impact of embedded factors like magnetic factor, wedge angle parameter Prandtl and Eckert numbers, Suction parameter, and thermal radiation on flow characteristics, temperature distribution, and the entropy generation are demonstrated. Entropy generation is compared for the convectional fluid, nanofluid, hybrid nanofluid, and THNF. Similarly, entropy generation for the downhill flow (m=−0.8), flat flow (m=0), Wedge flow (m=0.2), and stagnation flow (m=1) has been investigated for both suction (S=1) and injection (S=−1) and it has been observed that entropy generation is higher fir the THNF compared to other flows. Additionally, for confirmation, the present study is compared with published work.
