Output performance of a thermoelectric-based automotive waste heat recovery system with a nanofluid coolant is analyzed in this study. Comparison between Cu-Ethylene glycol (Cu-EG) nanofluid coolant and ethylene glycol with water (EG-W) coolant under equal mass flow rate indicates that Cu-EG nanofluid as a coolant can effectively improve power output and thermoelectric conversion efficiency for...

From the construction of the Casson invariant of homology spheres using intersection on configuration spaces, we propose a construction of an equivariant Casson invariant for a knot K homologous to 0 in rational homology sphere M . Our construction is adapted from C. Lescop ([7]) and use the same ideas in an equivariant setting. We show that the invariant we obtain is similar to the 2-loop part...

The pulsatile flow of blood through catheterized arteries is analyzed by treating the blood as a two-fluid model with the suspension of all the erythrocytes in the core region as a non-Newtonian fluid and the plasma in the peripheral layer as a Newtonian fluid. The non-Newtonian fluid in the core region of the artery is represented by i Casson fluid and ii Herschel-Bulkley fluid. The expression...

This contribution proposes two third-order numerical schemes for solving time-dependent linear and non-linear partial differential equations (PDEs). For spatial discretization, a compact fourth-order scheme is deliberated. The stability of the proposed set scalar equation, whereas its convergence specified system parabolic equations. applied to equation systems comprises governing heat mass tra...

In this paper, we investigate the effect of adding a stabilizer on the dynamic thermal properties of ZnO nanofluid (containing 5 to 10 nm diameter of ZnO nanocrystals) measured using a 3ω method. Addition of the stabilizer leads to the stabilization of the nanofluid and also substantial reduction of the enhancement of thermal transport compared to that seen in the bare ZnO nanofluid. This also ...

Forced convection boundary layer magnetohydrodynamic flow of a nanofluid over a permeable stretching plate is studied in this paper. The effects of suction-injection and viscous dissipation are taken into account. The nanofluid model includes Brownian motion and thermophoresis effects. The governing momentum, energy, and nanofluid solid volume fraction equations are solved numerically using an ...

In this paper the thermal convective instabilities of a binary nanofluid is theoretically investigated. In order to analyze a binary nanofluid, an addition factor is proposed under linear stability theory which is applied to the stability analysis of normal fluid. The factor describes the effect of nanoparticles on the convective instability of a basefluid. The Soret effect which represents the...

The goal of this paper is to experimentally study the behavior of nanofluid to improve the performance of a circular heat pipe. Pure water and Al2O3-water based nanofluid are used as working fluids. An experimental setup is designed and constructed to study the heat pipe performance under different operating conditions. The effect of filling ratio, volume fraction of nano-particle in the base f...

The physical aspects of inclined MHD nanofluid toward a stretching sheet embedded in porous medium were visualized, which has numerous applications industry. Two types nanoparticles, namely copper and aluminum oxide, used, with water (limiting case Casson liquid) as the base fluid. Similarity transformations used to convert partial differential equations into set ordinary equations. Closed solu...
