The implication of thermal radiation in a mixed convection hybrid nanofluid flow past an inclined stretching/shrinking sheet with mass suction

The impact of mass suction on the radiative flow through an inclined buoyancy force across a stretchable/shrinkable sheet induced by water-based Cu-Al₂O₃ hybrid nanofluids is numerically performed. The model (partial-differential equations) of the physical problem is reduced to the ordinary differential equation with an appropriate similarity variable. The reduced equations are then solved with the support of the bvp4c solver in MATLAB software. The multiple solutions for the velocity, temperature, skin friction, and heat transfer rate are acquired in the presence of physical parameters. The results suggest that enhancing the amount of Copper (Cu) nanoparticles decelerates both shear stress and heat capacity. Increasing the mixed convection parameter upsurges shear stress by about 3.32 % and heat transfer by 17.61 %, while a stronger stretching/shrinking parameter reduces shear stress by up to 9.71 %. In addition, an upsurge in suction leads to the boost of the first solution of the velocity profile but hinders the pace of the second solution of the velocity profile and both solutions on the temperature profile. The findings are validated with previous research and discussed through tables.
