Bödewadt Flow and Heat Transfer in Nanofluid over a Permeable and Radially Stretching Disk

A Bödewadt boundary layer flow and heat transfer problem in nanofluid was investigated this study for suction/injection as well combined effects of radial stretching disk. Similarity variables were introduced to transform the three-dimensional into a system ordinary differential equations. Moreover, similar viscous fluid, adequate suction is also required so that similarity solutions exist problems with no other such partial slip or Both disk can suppress natural oscillatory behavior apart from reducing momentum thermal thicknesses. As expected, injection acts oppositely. However, skin friction coefficient rate increase increasing parameters. stagnant disk, nanoparticle volume fraction enhance wall shear stress, whereas only when both are sufficiently small. For radially local Nusselt number increases. larger suction, smaller nanoparticles yielded enhanced than nanoparticles.
