Modeling magnetohydrodynamic ternary nanofluid flow over rotating porous discs with interfacial morphology effects

This work investigates the special thermophysical properties of ternary nanoparticles and suggests the best possible compositions for them. This study explores heat and mass transfer in viscous fluid flows driven by rotating porous discs, a key process in energy and chemical industries. Ternary nanoparticles greatly enhance the thermal characteristics of base fluids, which makes them useful for use in solar collectors, electronics, nuclear reactors, and energy storage. This study's examination of the interfacial morphology effects that occur between water and Cu, AlO3, and TiO2 nanoparticles in a flow between two rotating porous discs is a significant new breakthrough. Also taken into account are the effects of magnetic fields and permeability. The shooting method in conjunction with the RK scheme is used to solve the governing nonlinear PDEs once they have been converted to ODEs through the proper transformations. Soret number, Smidth Number and Dufour Number are benchmarked with previous findings to assure correctness, and comparative data visualization is used to highlight the findings. Extending previous research, it evaluates fluid dynamics under slip conditions, influencing heat and mass transfer rates. Key findings include a 15% reduction in wall shear stress with increasing slip length and a 25% enhancement in heat transfer efficiency compared to conventional fluids. Wall velocity distribution (related to disc rotation), thermal and solutal diffusion under MHD effects and temperature and concentration gradients in the nano-layer.
