Abstract This study investigates the enhancement of heat transfer for fluid with addition nano-particles in a two-dimensional rectangular cavity. Thermo-physical properties such fluids and volume fraction those its characteristics are studied. ANSYS Fluent code is utilized this purpose. Validation computational model has been carried out against benchmark data available from literature. A corre...
Abstract
In the present attempt, flow behavior and thermal convection of one type of nanofluids in a disc geometry was investigated using Computational Fluid Dynamics (CFD). Influence of gravity induced sedimentation also has been studied. The commercial software, Fluent 6.2, has been employed to solve the governing equations. A user defined function was added to apply a uniform external ma...
Based on the model of battery temperature rising established, several kinds of temperature rising processes are analyzed by means of numerical simulation including heat dissipation by natural convection without fin or with fin and forced convection with fin. The comparison and analysis are made for temperature rising process about their temperatures of center and across section plane. It shows ...
In this paper we present lattice Boltzmann (LB) schemes for convection diffusion coupled to fluid flow on two-dimensional rectangular lattices. Via inverse Chapman-Enskog analysis of LB schemes including source terms, we show that for consistency with physics it is required that the moments of the equilibrium distributions equal those of the Maxwell-Boltzmann distribution. These constraints can...
