Heat transport phenomenon of the MHD water-based hybrid nano°uid °ow over a rotating disk with velocity slips

The present investigation computes the heat transport phenomenon of the magnetohydrodynamic (MHD) °ow of CuO-Ag/H₂O hybrid nano°uid over a spinning disc. The authors are con¯dent that there is very less analysis covering the °uid °ow containing silver and copper oxide nanoparticles over a rotating disk. Therefore, the authors are interested to consider the water-based nanoliquid °ow over a spinning disk. Furthermore, the velocity slip and thermal convective conditions are taken into consideration. The formulation of the problem is made in the form of PDEs and is then converted into the nonlinear ODEs by employing suitable similarity transformations. The homotopic analysis approach is applied for the semi-analytical solution of these resulting equations. The convergence of homotopic approach has also revealed with the help of ¯gure. The performance of the hybrid nano°uid °ow velocities and temperature has been shown in a graphical form against distinct °ow parameters. Also, the numerical results of skin friction coe±cient and Nusselt number have been calculated in a tabular form. The outcomes of the current problem show that the increase in the skin friction of the water-based copper oxide nano°uid is greater than the water-based silver nano°uid at 4% of the nanoparticle volume fraction. Also, the skin friction of the hybrid nano°uid is increased by 8% compared to the silver nano°uid at 4% of the nanoparticle volume fraction. Furthermore, the heat transfer rate of the water-based copper oxide nano°uid is greater than the water-based silver nano°uid at 4% of the nanoparticle volume fraction. Also, the heat transfer rate of the hybrid nano°uid is 52% greater than that of silver nano°uid at 4% of the nanoparticle volume fraction. It is found that the Nusselt number of the hybrid nano°uid is highly a®ected by the embedded parameters as compared to nano°uids.
