要約
Laser Doppler velocimetry (LDV) was employed to investigate flow and its oscillatory behavior in the intersecting region of converging-diverging duct pairs. Both the converging and diverging angles were varied, as were the flow rate through the intersecting region. Velocity vector and power spectrum distributions were obtained from the LDV measurement, from which the distributions of vorticity, Reynolds stress, and lateral and longitudinal turbulence intensity were calculated. The mechanism of dissipation of kinetic energy resulting from the collision of two converging streams and the mechanism of convective heat transfer performance in a flow network are explained.
