Computational analysis of non-Newtonian boundary layer flow of nanofluid past a semi-infinite vertical plate with partial slip

Abstract

An analysis of this paper is examined, two-dimensional, laminar with heat and mass transfer of natural convective nanofluid flow past a semi-infinite vertical plate surface with velocity and thermal slip effects are studied theoretically. The coupled governing partial differential equations are transformed to ordinary differential equations by using non-similarity transformations. The obtained ordinary differential equations are solved numerically by a well-known method named as Keller Box Method (KBM). The influences of the emerging parameters i.e. Casson fluid parameter (β), Brownian motion parameter (Nb), thermophoresis parameter (Nt), Buoyancy ratio parameter (N), Lewis number (Le), Prandtl number (Pr), Velocity slip factor (Sf) and Thermal slip factor (ST) on velocity, temperature and nano-particle concentration distributions is illustrated graphically and interpreted at length. The major sources of nanoparticle migration in Nanofluids are Thermophoresis and Brownian motion. A suitable agreement with existing published literature is made and an excellent agreement is observed for the limiting case and also validation of solutions with a Nakamura tridiagonal method has been included. It is observed that nanoparticle concentrations on surface decreases with an increase in slip parameter. The study is relevant to enrobing processes for electric-conductive nano-materials, of potential use in aerospace and other industries.

Finite Element Simulation of Multiple Slip Effects on MHD Unsteady Maxwell Nanofluid Flow over a Permeable Stretching Sheet with Radiation and Thermo-Diffusion in the Presence of Chemical Reaction

“…It was found that when the flow pressure is low, the slip boundary condition is necessary. A slip condition on stretching or shrinking surfaces is used by several researchers [15][16][17][18][19]. Ramaya et al [15] analyzed the nanofluids through a stretching sheet.…”

“…Extend the work of Raju et al 7 and Tamoor et al 8 to MHD fluid flow on moving over the porous stretching plate with Casson fluid using the Kellarbox technique is discussed by Ullaha et al 9 Amanulla et al 10 discussed thermal and nanoliquid flow across a vertical plate, and they discovered that the slip parameter reduces concentration profiles. The physical problems of MHD and complexity of solutions of nonlinear partial differential equations (PDEs) over the plate, moving plate, with ramped wall temperature, rotating disc, exponentially porous stretching plate, and chemical molecular diffusivity are discussed in Amanullah et al, 10 Onyejekwe, 11 Kataria and Patel, 12 Alreshidi et al, 13 Reddy et al, 14 and Haq et al, 15 respectively. Nowadays many industries are facing the complexity of computing the thermal diffusion and the diffusion-thermo in energy flux caused by concentration differences.…”

Insight into the dynamics of non-Newtonian Casson fluid over a rotating non-uniform surface subject to Coriolis force

“…Casson uid model is one of the non-Newtonian uids which models uids such as jelly, honey, fruit juices, soup, and blood etc. Casson uid is a shear-thinning uid exhibiting yield stress and which has in nite viscosity at a low shear rate and zero viscosity at the in nity shear rate; RamReddy et al [15] and Amanulla et al [16]. In other words, Casson uid behaves like a solid when yield stress is more than the shear stress but behaves like a liquid and ows when the yield stress is less than the shear stress.…”
