Numerical Simulation of Buoyancy A ected Turbulent Air Flow in a Room


Department of Mechanical Engineering,Sharif University of Technology


In this paper, a three-dimensional steady state incompressible turbulent air
ow is considered in
a large single room. The buoyancy a ected turbulent air
ow is numerically simulated by solving
governing equations. The turbulence modeling includes both k ???? " and zero-equation models
and their results are compared to the experimental data. The paper reviews several aspects,
such as displacement of radiator system performance, temperature and
ow eld distribution
and comfort conditions. The results show that the best temperature distribution and comfort
condition are obtained when the radiator is installed under the window and its height is equal to
or greater than that of the window.
