| description | This thesis studies the flow and heat transfer characteristics of steady Bödewadt flow in nanofluid and hybrid nanofluid with the presence of suction on the radial stretching permeable disk. Bödewadt flow is a rotating flow that is induced by a rotating source that is placed far away from the bottom disk. In this study, the role of nanofluid in heat transfer enhancement are theoretically investigated. The nanoparticles that considered in this study are copper, silver, and aluminium oxide while the base fluid is water. By using the similarity variables, the governing partial differential equations are reduced to nonlinear ordinary differential equation which are then numerically solved using the Keller’s Box method. Adequate amount of suction was needed for the similarity solution of heat transfer equation to exist in the case of stagnant disk. The presence of suction and stretching disk caused the momentum and thermal boundary layer thickness to reduce. Both nanofluid and hybrid nanofluid helps in increasing the local skin friction coefficient and local Nusselt number better than viscous fluid. However, the heat transfer enhancement occurs only when volume fraction of nanoparticle is sufficiently small due to the presence of suction. The presence of the second nanoparticles in hybrid nanofluid showed that the heat transfer enhancement is better compared to nanofluid. Same as the case of nanofluid, sufficiently amount of suction and stretching disk need to be applied in order to enhance the heat transfer rate. |
