Revolutionizing Heat Transfer: Unveiling the Dynamic Symphony of Tri-Hybrid Nanofluids between Rotating Coaxial Porous Discs

Abstract

We examine the physical model of a time-dependent, laminar, compressible flow of tri hybrid nanofluids in two dimensions within two coaxial rotating porous discs. Both the upper and lower discs have a length of 2s(t).The two axial and radial components (u, w) are dependent upon the direction normal z and the discs radial r. For both the upper and lower discs, there is a constant temperature (T1 >T2) . The continuity, momentum, and energy equations are modeled using the cylindrical coordinate system. The numerical solutions are evaluated using the finite element method. It has been noted that as the magnetic parameter values increase, the velocity near the upper and lower discs decreases. The thermal conductivity (THDnf) of the nanoparticles decreased as their shape factor (NS) increased. Shear stress and heat transfer rate decrease under the influence of α (shrink/spread) volumetric function parameters (θ1 , θ2 and θ3), but an opposite response is observed when the values of M (magnetic parameter), Re (Reynold Number), and NS (nano particles shape factor) increase.
