MHD Cattaneo-Christove flow of Casson nanofluid over a porous surface: A solar application

Researchers are giving close attention to Casson liquid owing to their significant solicitations in engineering and industrial processes including food dispensation, polymer extrusion, and ink production. In this paper, magnetohydrodynamic (MHD) Cattaneo–Christove flow of Casson nanofluid over a stretched exterior in the turnout of heat sink/source is examined. Double solutions are presented for Al–Cu–H 2 O and Al–H 2 O nanofluids. The governing flow equations are mutated into ODEs with the aid of similarities and then cracked numerically by R.K. process. The slip condition is applied to the momentum boundary, while a convective condition is considered for the thermal boundary layer. Plots are pinched to distinguish the impact of numerous parameters on the flow fields. The consequences reveal that the heat function is a growing function of magnet field and heat sink/source parameters for both Al–Cu–H 2 O and Al–H 2 O nanofluids. The measure of heat transport is elevated in the case of Al–Cu–H 2 O as contrasted to Al–H 2 O. Increasing the thermic relaxation constraint, the temperature decreases. This result is useful in designing systems like solar collectors and spacecraft thermal shields, where managing radiative heat loss is critical to maintaining optimal temperatures.
