Comparative analysis of penta-hybrid and ternary hybrid nanofluids in a rotating porous stretchable channel with mhd and thermal radiation effects

Abstract

This work examines the ternary hybrid nanofluid and the penta hybrid nanofluid flow in a porous and stretchable rotating channel with the dual effects of magnetic fields, thermal radiation, chemical reactions, and internal heat generation. The nonlinear differential equations governing the flow are dimensioned with similarity variables and solved with the bvp4c solver in MATLAB. The main thermofluid parameters such as velocity components, temperature and concentration distributions, wall shear stress, and the Nusselt number are examined in the context of various parameter values. As Reynolds number increases, the velocity profile decreases. As Reynolds number increases, the temperature and concentration profiles also decrease. The results show that improving rotation parameter reduces transverse velocity while improving the temperature profile. Increasing the suction parameter reduces the concentration. Also, increasing the stretching ratio parameter improves the temperature. The results indicate the skin friction coefficient to be reduced in penta hybrid nanofluid compared to ternary hybrid nanofluid. Also, the Nusselt number is enhanced in penta hybrid nanofluid compared to ternary hybrid nanofluid. These results are important contributions to enhancing the efficiency of heat and mass transfer technologies in high-technology industries. Practical implications of this study find applications in the optimization of cooling systems in high-performance electronics, energy conversion in solar thermal collectors, chemical processing heat exchangers, and thermal management in the case of rotating machinery and microfluidic devices.
