The present work carries out a three-dimensional numerical analysis study of Aluminium Nitride (AlN)-water hybrid nanofluid enhanced heat transfer in laminar forced convection flow exchanger with four different channels, flat, backward facing step, triangle and trapezoidal step channels. influence Reynolds number (100≤ Re ≤1500) solid nanoparticles volume fraction (1% 4%) on the fluid were nume...

At the outset, this work aims to carried out an analytical investigation of forced convection by establishing a laminar flow into circular duct under convective boundary conditions third type for non-Newtonian nanofluid, fluid containing TiO2 uniformly dispersed in aqueous solution with 0.5wt% CMC solutions (Carboxymethyl Cellulose) is used as working fluid. The viscous dissipation effects are ...

In this study, mixed convection heat transfer and local and global entropy generation in aventilated square cavity have been investigated numerically. The natural convection effect isachieved by a constant heat flux imposed at the bottom wall and cooled by injecting a coldfollow. In order to investigate the effect of port location, four different placementconfigurations of the inlet and outlet ...

This paper considers an important model of boundary value problem with a condition at infinity namely combined free and forced convection over a plane of arbitrary shape embedded in a fluid-saturated porous medium; this model admits dual solutions, and uses a technique, which is to some extent modification of homotopy analysis method (HAM), in order to obtain dual solutions analytically with hi...

The interaction of thermal radiation with conduction and laminar natural convection in a vertical circular pin, situated at participating gas, is numerically investigated. An absorbing and emitting gas is considered, and treated to be a gray participating media. Under the idealizing of gray gas, the Rosselan4 approximation is employed to describe the radiative heat flux in the energy equation. ...

this paper was concerned with studying the magnetohydrodynamic steady laminar free convection flow of a micropolar fluid past a continuously moving surface in the presence of heat generation and thermal radiation. similarity transformation was employed to transform the governing partial differential equations into ordinary ones, which were then solved numerically using the finite element method...

A model for heat-recirculating micro combustor is developed. It investigates the structure of laminar, one-dimensional and steady state flame propagation in uniformly premixed wood particles with considering the effects of heat recirculation caused by configuration of micro combustor. The flame structure is divided into three regions: a preheat-devolatilization zone where the rate of the gas-ph...

The enhancement of the heat transfer in stirred tank is a much-desired objective for accelerating certain physical and chemical parameters industrial field. From this basis, an attempt made paper to investigate effect wavy wall on hydrodynamic, thermal, energetic behavior Al2O3-Water nanofluid. has flat bottom, it equipped with anchor stirrer. A hot temperature been imposed wall, agitator assum...
