A study of natural convection heat transfer in a nanofluid filled enclosure with elliptic inner cylinder
Tập 24 Số 8 - Trang 1906-1927 - 2014
Purpose – The purpose of this paper is to study the effects of natural
convection heat transfer in a cold outer circular enclosure containing a hot
inner elliptic circular cylinder. The fluid in the enclosure is Cu-water
nanofluid. The main emphasis is to find the numerical treatment for the said
mathematical model. The effects of Rayleigh number, inclined angle of elliptic
inner cylinder, effecti...
Meshless local radial basis function collocation method for convective‐diffusive solid‐liquid phase change problems
Tập 16 Số 5 - Trang 617-640 - 2006
PurposeThe purpose of this paper is to develop a new local radial basis function
collocation method (LRBFCM) for one‐domain solving of the non‐linear
convection‐diffusion equation, as it appears in mixture continuum formulation of
the energy transport in solid‐liquid phase change
systems.Design/methodology/approachThe method is structured on multiquadrics
radial basis functions. The collocation is...

Purpose The purpose of this paper is to present the investigation of the
pressure-driven flow of aluminum oxide-water based nanofluid with the combined
effect of entropy generation and radiative electro-magnetohydrodynamics filled
with porous media inside a symmetric wavy channel. Design/methodology/approach
The non-linear coupled differential equations are first converted into a number

Effects of magnetic field on micro cross jet injection of dispersed nanoparticles in a microchannel
Tập 30 Số 5 - Trang 2683-2704 - 2020
Purpose Water/Al2O3 nanofluid with volume fractions of 0, 0.3 and 0.06 was
investigated inside a rectangular microchannel. Jet injection of nanofluid was
used to enhance the heat transfer under a homogeneous magnetic field with the
strengths of Ha = 0, 20 and 40. Both slip velocity and no-slip boundary
conditions were used. Design/methodology/approach The laminar flow was studied
using Reynolds nu...

Purpose This paper aims to numerically investigate the natural convection heat
transfer of a hybrid nanofluid into a porous cavity exposed to a variable
magnetic field. Design/methodology/approach The non-linear elliptical governing
equations have been solved numerically using control volume based finite element
method. The effects of different governing parameters including Rayleigh number

Energetic-exergetic analysis of an air handling unit to reduce energy consumption by a novel creative idea
Tập 29 Số 10 - Trang 3959-3975 - 2019
Purpose This study aims to simulate the flow and heat transfer through an air
handling unit to reduce its energy consumption by a novel creative idea of using
an air-to-air heat exchanger. Design/methodology/approach To do this, both first
and second laws of thermodynamics energy and exergy balance equations were
solved numerically by an appropriate developed computer code. Findings Using the
air-...
Three dimensional flow of an Oldroyd-B fluid with Newtonian heating

Purpose – The purpose of this paper is to analyze the boundary layer flow of an
Oldroyd-B fluid with Newtonian heating. Design/methodology/approach – Series
solutions are found by homotopy analysis method. Findings – Temperature profile
increases with an increase in conjugate parameter. Increase in parameter β and
Prandtl number Pr decreases the temperature profile. Originality/value – This
work d...
