Boundary layer Darcy-Forchheimer couple stress hybrid nanofluid flow over a quadratic stretching surface due to nonlinear thermal radiation

The present investigation offers a systematic assessment of CuO + MWCNTs, MgO + MWCNTs, hybrid nanofluids and MWCNT nano liquid motion in direction of porous stretching and shrinking sheet. Water is utilized as the base fluid, and nanomaterials are comprised of CuO, MgO, and MWCNTs. The leading model nonlinear coupled PDEs are first transformed into nonlinear coupled ODEs employing similarity transformation, and afterward, the resultant highly nonlinear coupled ODEs are solved analytically. Also, the shear stress of the wall passed a sheet that was shrinking increase by approximately 6.3% and 12.6% when the nanoparticle concentration increases from 0% to 2% and 4%, respectively. The figures show that the nanoparticle volume fraction and thermal radiation serve as helping parameters in determining the temperature. It is concluded from the obtained results that (3%Wt) MgO + MWCNTs is more effective than the (4%wt) of the CuO + MWCNTs for the enhancement of the heat transfer rate.
