Impact of thermal radiation and internal heat generation on Casson nano-fluid flowing by a curved stretchable surface with suspension of carbon nanotubes (CNTs)

Abstract

The function of present work is to inspect heat transmission of radiative nanofluid in regard to boundary layer description. Carbon nanotubes (CNTs) dependent fluid is being evaluated and it flows overtop a curved stretching 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 (base fluid) have been utilized for the composition of nanofluid. The rheological properties of blood have been captured using Casson fluid model. Appropriate transformations have been applied to reduce the modeled 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.
