Lattice Boltzmann Simulation of Nanofluids Natural Convection Heat Transfer in Concentric Annulus (TECHNICAL NOTE)
Abstract This study is applied Lattice Boltzmann Method to investigate the natural convection flow utilizing nanofluids in a concentric annulus. A numerical strategy presents for dealing with curved boundaries of second order accuracy for both velocity and temperature fields. The fluid between the cylinders is a water-based nanofluid containing different types of nanoparticles: copper (Cu), a...
متن کاملHeat Transfer Coefficients Investigation for TiO2 Based Nanofluids
From a regression analysis perspective, this paper focused on literature about TiO2 nano particles. The particles on focus entailed those that had been suspended in ethylene glycol and water – at a ratio of 60:40. Indeed, regression analysis has gained application in contexts such as the turbulent Reynolds number, especially with the aim of establishing the impact of the ratio of the...
متن کاملForced Convection Heat Transfer of Giesekus Viscoelastic Fluid in Concentric Annulus with both Cylinders Rotation
A theoretical solution is presented for the forced convection heat transfer of a viscoelastic fluid obeying the Giesekus constitutive equation in a concentric annulus under steady state, laminar, and purely tangential flow. A relative rotational motion exists between the inner and the outer cylinders, which induces the flow. A constant temperature was set in both cylinders, in this study. The f...
متن کاملCouette-Poiseuille Flow of Non-Newtonian Fluids in Concentric Annuli
Two types of laminar flows of non-Newtonian fluids in annuli with stationary outer cylinder are analysed from the viewpoint of existence of an exact analytical or almost exact analytical (quasisimilarity) solution relating volumetric flow rate and axial pressure gradient. The exact analytical solution is derived for the Vocadlo (RobertsonStiff) fluids when flow is caused simultaneously by the i...
متن کاملExperimental Investigation on Heat Transfer of Silver-Oil Nanofluid in Concentric Annular Tube
In order to examine the laminar convective heat transfer of nanofluid, experiments carried out using silver-oil nanofluid in a concentric annulus with outer constant heat flux as boundary condition. Silver-oil nanofluid prepared by Electrical Explosion of Wire technique and observed no nanoparticles agglomeration during nanofluid preparation process and carried out experiments. The average size...
