EFFECTS OF WALL CONCAVITY ON OSCILLATIONS OF JET STREAMS FROM DIAMOND-SHAPED CYLINDER BUNDLES
RESUMO
The promotion of jet-stream diffusion may enhance the efficiency of mechanical performance in various industrial devices such as fluid machinery and combustion equipment. Both active and passive means were applied for the control of jet streams. Our previous studies disclosed that diamond-shaped cylinder bundles produce a self-excited oscillating jet-stream flow field having multiple uniform flow-rate groups. The present visualization work deals with flip-flop flow oscillation from a diamond-shaped cylinder bundle with wall concavity. It is disclosed that the presence of wall concavity resulted in a remarkable change in the jet-stream from the diamond-shaped cylinder bundle in higher turbulence levels and dispersion of individual jet-streams with respect to those without concavities.
