Numerical study a flow around a heated finite cylinder and mounted vertically on a flat plate

Authors: , ,

Abstract: Flow around a finite end cylinder mounted vertically on a flat plate and thermally heated is simulated numerically by the Large-Scale Simulation (LES) approach. The flow is in subcritical regime circulate with a velocity U∞=0.54m/s corresponding a Reynolds number ReD=2.2x104. The boundary condition of Neumann is imposed on the surface of the cylinder, which is reflected by a density of the heat flux is = 600W/m2, for an aspect ratio H/D=5.This simulation induces a complex structure of the flow behind the cylinder, in particular the appearance of vortices and recirculation zones ahead and behind it. The results obtained give a clear comparison with those found experimentally and numerically of Guillermo Palau- Salvador et al. [2], that were carried out its work in the case of adiabatic flow
