| description | This work is the subject of an experimental and a numerical study of a system
of swirling jets system impinging a plane wall. The experimental test bench
comprising three diameter D diffusers, which are 2D distant between the axes,
impacting perpendicular plate, by setting the impact height H = 4D. The swirl
is obtained by a generator (swirl) of compound 12 fins arranged at 60 °
relative to the vertical placed just at the exit of the diffuser. A portable
VELOCICALC PLUS anemometer device at various stations measures the
blowing temperature of the swirling jets hitting the plate. The results of this
study have shown that, the global jet has the same characteristics as a free jet,
close to the obstacle it undergoes a considerable deviation characterized by
the weakening of the temperature and the speeds then the development of the
jet. The temperature amplitudes decrease, as we approach the plate. The
velocity profiles show that velocity changes direction and increases radially.
The Nusselt number is moderate at the level of the impact surface ensuring the
homogenization of the heat transfer of the plate. The system was simulated
numerically by the Fluent program based on the turbulence model (k-epsilon).
The latter gave results of temperature and velocity fields having profiles in line
with those of experimental results. |
