Mixed Convection Flow of Viscoelastic Nanofluid Past a Horizontal Circular Cylinder with Viscous Dissipation

Abstract

The purpose of this study was to examine the effect of viscous dissipation on mixed convection flow of viscoelastic nanofluid past a horizontal circular cylinder. Carboxymethyl cellulose solution (CMC) is chosen as the base fluid and copper as a nanoparticle with the Prandtl number Pr = 6.2. The transformed boundary layer equations for momentum and temperature subject to the appropriate boundary conditions are solved numerically by using Keller-box method. The influenced of the dimensionless parameters such as Eckert number, mixed convection parameter, nanoparticles volume fraction and viscoelastic parameter on the flow and heat transfer characteristics is analyzed in detail and presented graphically. The results come out with the velocity profiles are increased while the temperature profiles are decreased by increasing the values of nanoparticles volume fraction and viscoelastic parameter, respectively. The graph shows that, increasing Eckert number the skin friction is also increases. The values of skin friction are increased by increasing mixed convection parameter, but the values of Nusselt number produce an opposite behavior. The present study has many applications especially in heat exchangers technology and oceanography. Therefore, in future, it is hoping to study the viscoelastic nanofluid flow past a different geometric such as sphere and cylindrical cone.

Thermal Marangoni Flow Past a Permeable Stretching/Shrinking Sheet in a Hybrid Cu-Al2O3/Water Nanofluid

“…Polymer melts, paints, biological solutions, tars and glues are among the non-Newtonian fluid which are widely used in the industrial and technological operations. The significant impact of the magnetic field and temperature dependent viscosity using non-Newtonian nanofluid inside a pipe was analyzed by Ellahi (2013) while Mahat et al (2018) analyzed the mixed convective flow of viscoelastic nanofluid towards a circular cylinder with the consideration of viscous dissipation effect. Recently, the analysis on momentum and heat transfer of MHD Carreau nanofluid over a stretching plate was conducted by Yousif et al (2019).…”

Three-Dimensional Bioconvection Nanofluid Flow from a Bi-Axial Stretching Sheet with Anisotropic Slip

“…Anisotropic slip bioconvection nanofluid flows have been addressed by Raees et al (2016) and Uddin et al (2016). Recently, several nanofluid flows past a surface (movable/non-movable) are inspected under various physical constraints (for fluid flow) (Akbarzadeh et al 2018;Alamri et al 2019;Aziz et al 2018;Hassan et al 2018aHassan et al , 2018bHussain et al 2018;Jamaludin et al 2018;Mahat et al 2018;Rashidi et al 2018;Shehzad et al 2018;Zeeshan et al 2018).…”

Lower Stagnation Point Flow of Convectively Heated Horizontal Circular Cylinder in Jeffrey Nanofluid with Suction/Injection

“…Here, the Carboxymethyl cellulose (CMC) water represents based fluid while copper signifies nanoparticles. The closely related existing publications were from Zokri et al, [26] and Mahat et al, [27].…”

“…Zokri et al, [26] implemented the Buongiorno model to investigate the Jeffrey nanofluid model with viscous dissipation effect. Very recently, Mahat et al, [27] adopted the Tiwari and Das model to examine the copper and Carboxymethyl cellulose (CMC) water in viscoelastic nanofluid model. Driven by the discussions pointed out above, it is clear that the Jeffrey nanofluid flow passing through horizontal circular cylinder has so far never been investigated using the Tiwari and Das model.…”
