Heat transfer to proximal cylinders in hypersonic flow

fluctuating flow characteristics and heat transfer from two in-tandem square cylinders

in this paper, the flow around bluff bodies with different cross sections and determination of forces acts on them are investigated.this paper presents the results of a numerical study on the flow characteristics and heat transfer over two equal square cylinders in a tandem arrangement. spacing between the cylinders is 5 widths of the cylinder and the reynolds number ranges from 1 to 200, pr=0....

Forced Convection: Heat Transfer from Copper Cylinders to Air

Three copper cylinders of diameter 1/4”, 3/8” and1/2” were heated and then immersed in an air stream flowing through a cylindrical pipe. The temperature change of the cylinders with respect to time was measured at different air flow rates. With this data, the Nusselt, Reynolds and Prandtl numbers were calculated and correlated. This correlation was compared to ones established by Sherwood-Pigfo...

Using Burnett Equations to Derive an Analytical Solution to Pressure-Driven Gas Flow and Heat Transfer in Micro-Couette Flow

The aim of the present study is deriving an analytical solution to incompressible thermal flow in a micro-Couette geometry in the presence of a pressure gradient using Burnett equations with first- and second-order slip boundary conditions. The lower plate of the micro-Couette structure is stationary, whereas the upper plate moves at a constant velocity. Non-dimensional axial velocity and tempe...

Heat Transfer to Separation Flow in Heat Exchangers

Flow Analysis Heat and Mass Transfer in a Room

This reports the study on the flow behaviour, heat transfer and contamination distribution in a room. For this purpose the 3-D incompressible Navier-Stokes equations, energy equation and a mass transfer equation which model the concentration of contamination have been applied. For turbulence simulation the two equation standard k-  turbulence model was employed. By means of SIMPLE algorithm the...
