Suspended nanoparticles on mixed convection flow of a Jeffrey fluid due to a horizontal circular cylinder with viscous dissipation

Abstract

The non-Newtonian Jeffrey fluid model describes the viscoelastic property that elucidates the dual components of relaxation and retardation times. Nonetheless, there has been considerable attention on its unsatisfactory thermal performance. The model of nanofluid is contemporarily in the limelight due to its superior thermal performance compared to the conventional fluid. The proposed study herein aims to examine the Jeffrey nanofluid model over a horizontal circular cylinder with mixed convection flow. The flow analysis is performed based on the Buongiorno model with the integration of Brownian motion and thermophoresis diffusion parameters. The influence of frictional heat is also accounted. The nondimensional and non-similarity transformation variables are utilized to reduce the dimensional governing equations into three non-dimensional partial differential equations (PDEs). Subsequently, the obtained PDEs are tackled numerically through the Keller-box method. Certain continent parameters are investigated with regards to the identified distributions. A comparative study is executed based on previous studies, which indicates good agreement with results of the current study. The findings specify that the transition of boundary layer from laminar to turbulent flows happens for dissimilar values of mixed convection parameter, Deborah number, Brownian motion and Eckert number. In particular, the boundary layer separates from cylinder for positive (heated cylinder) and negative (cooled cylinder) values of mixed convection parameter. Heating the cylinder defers the separation of boundary layer, while cooling the cylinder carries the separation point close to the lower stagnation point.

The Thematic Review on Convective Heat Transfer of Nanofluid over Horizontal Circular Cylinder

“…The model of non-Newtonian Jeffrey fluid is known for its ability to describe viscoelastic property, namely the dual components of retardation and relaxation times [44]. There are three articles that used Jeffrey Nanofluid and all of them are produced by Zokri et al, [44][45][46]. Two of them are based on Buongiorno model and the other one is based on Tiwari and Das model.…”

“…This framework empowers researchers and engineers to comprehend and predict the flow characteristics of such fluids in diverse scenarios. Mohd et al [22] studied the behavior of suspended nanoparticles within the context of mixed convection flow of a Jeffrey fluid induced by a horizontal circular cylinder, considering the effects of viscous dissipation. Recently, Raje et al [23] investigated the entropy generation associated with the flow of Jeffrey fluid through an inclined pipe of circular cross-section, taking into account the presence of a uniform porous medium.…”
