Abstract
Both exptl. and numerical techniques are used to study the vortex formation process behind a heated circular cylinder. The hydrogen bubble visualization expts. are executed to investigate the evolution of the shedded structures while preliminary Particle Tracking Velocimetry (PTV) data and 2-D Spectral Element Method (SEM) calcns. are used to investigate the vortex formation process under influence of the induced heat. The typical value for the Reynolds no. ReD is equal to 73 and the Richardson no. RiD is varied between 0 and 1.5. The purely forced convection vortex shedding mechanism for low Reynolds nos. as described by Green and Gerrard (1993) is used as starting point for this investigation. The obsd. effects of the induced heat are an increasing difference in strength between the upper and lower vortex rows and for higher RiD nos. the early break down of the Von Karman vortex street
