Abstract
This work aims to examine the flow of tangent hyperbolic (T-H) ternary hybrid nanofluid (THNF) over a rough-yawed cylinder generated by impulsive motion in a mixed convection mechanism with periodic magnetohydrodynamics. The surface roughness is depicted by a high-frequency sine wave with a small amplitude. The governing equations of a system were converted to a dimensionless form by using semi-similar transformations. After linearizing the equations with a Quasilinearization technique, they were discretized with the implicit finite difference method. Including a third component (i.e. MoS2) of the THNF decays the fluid velocity. Raising magnetic field parameter M from 0 to 2 boosts the Rex1/2Cf for THNF by 19% at ξ=0.55. The Rex1/2Cf increases to a maximum of 288% for the T-H and 101% for the Newtonian THNF as the roughness attribute ϵ increases from 0.001 to 0.01 for ξ=0.31 at n=15. The findings were compared to previously published to demonstrate the numerical method's reliability.
