Tangent hyperbolic ternary hybrid nanofluid flow over a rough-yawed cylinder due to impulsive motion

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 (Formula presented.) for THNF by 19% at (Formula presented.). The (Formula presented.) increases to a maximum of 288% for the T-H and 101% for the Newtonian THNF as the roughness attribute (Formula presented.) increases from 0.001 to 0.01 for (Formula presented.) at (Formula presented.). The findings were compared to previously published to demonstrate the numerical method's reliability.
