Thermal analysis for Casson fluid flow over a curved stretchable surface with carbon nanotubes suspension

Abstract

In this thesis heat transmission of non-Newtonian radiative nanofluid flows is inspected with reference to boundary layer description. Carbon nanotubes (CNTs) dependent fluids are being evaluated by considering the geometry of curved stretchable surface. Special features, like thermal radiation and internal heat generation, which corresponds to heat transmission along the flow have been incorporated. Dual nature of carbon nanotubes, that is, single walled carbon nanotubes (SWCNTs) as well as multiple walled carbon nanotubes (MWCNTs) together with blood and slurry mixture (base fluids) have been utilized for the composition of nanofluid. In order to capture the rheological properties of blood, Casson fluid model has been deployed. Likewise, second-grade model has been engaged to capture the rheological properties of slurry mixture. Appropriate similarity transformations have been applied to reduce the modelled system of nonlinear partial differential equations into a system of ordinary differential equations (ODEs). To achieve the desired numerical solution of obtained system of ODEs, NDSolve technique is employed using Mathematica. Numerous parameters appearing in governing equations, exert influence on focused physical quantities. Graphs have been engaged to capture these variations for both SWCNTs and MWCNTs. Likewise, numeric charts have been displayed to investigate impressions on skin friction coefficient and Nusselt number for distinct parameters.
