要約

An experimental and numerical investigation of natural convection in an attic-shaped triangular cavity in winter or nighttime conditions was carried out. The cavity had three isothermal, aluminum walls and a Plexiglas wall. The experimental method used was Particle Image Velocimetry and Fluent 12.1.4 was the numerical software employed. The range of Rayleigh numbers analyzed was from 5·105 to 1·107. The isotherms, velocity maps, and streamlines produced were examined and studied. The results show that for Ra < 6.0·106 two main vortices develop in the enclosure while for Ra > 6.0·106 a third vortex begins to form.
