Radiation Effect on Mixed Convection Boundary Layer Flow of a Viscoelastic Fluid over a Horizontal Circular Cylinder with Constant Heat Flux

Abstract

In the present article, radiation effect on mixed convection boundary layer flow of a viscoelastic fluid over a horizontal circular cylinder with constant heat flux has been numerically analyzed. The governing boundary layer equations are transformed to dimensionless nonlinear partial differential equations. The equations are solved numerically by using Keller-box method. The computed results are in excellent agreement with the previous studies. Skin friction coefficient and Nusselt number are emphasized specifically. These quantities are displayed against the curvature parameter. The effects of pertinent parameters involved in the problem namely effective Prandtl number and mixed convection parameter on skin friction coefficient and Nusselt number are shown through graphs and table. Boundary layer separation points are also calculated with and without radiation and a comparison is shown. The presence of radiation helps to decrease or increase the skin friction coefficient for the negative or positive values of the mixed convection parameter accordingly . The decrease in value of effective Prandtl number helps to increase the value of skin friction coefficient and Nusselt number for viscoelastic fluids.

Mixed convection flow of an electrically conducting viscoelastic fluid past a vertical nonlinearly stretching sheet

“…In addition to exhibiting both viscosity and elasticity, one category of non-Newtonian fluids with dual effect features is viscoelastic fluid (i.e., heat transfer reduction and drag reduction properties) 14 , which contributes to a wide range of applications in the polymer industry. Manufacture of paper, fibre glass, dyes, films, extraction processes, copper wire thinning and hardening, synthetic fibre and plastic film processing, drawing of plastic sheet, cooling of metallic chips, and food processing are all included in this 15 . In the process engineering of oil reservoirs, bio-engineering, the chemical industry, and nuclear technology, viscoelastic fluid is also crucial.…”

“…They observed that a reduction in heat transfer processes results from an increase in the radiation parameter. Many studies, like Raja et al 7 , Datti et al 11 , and Ahmad et al 15 , have considered the impact of radiant heat on boundary layer flow induced by a nonlinearly stretching sheet because of its significance in controlling and maintaining the system's temperature.…”

“…The study of non-Newtonian fluid fascinates researchers due to daily life significance in, and pastes, paints, biological fluids, motor oils, mechanical procedures, and complex mixtures.
