英文摘要
Understanding turbulence kinetic energy (TKE) budget in gas-liquid two-phase bubbly flows is indispensable to develop and improve turbulence models for the bubbly flows. Simultaneous measurement of velocity and velocitygradients with a spatial resolution smaller than the Kolmogorov scale is required to evaluate the TKE budget experimentally. We therefore improved a molecular tagging velocimetry based on photobleaching reaction (PB-MTV) to accurately evaluate TKE budget. We measured TKE budget in a turbulent water flow and bubbly flows in a square duct by using the PB-MTV to examine effects of bubbles on TKE budget. The experimental results will contribute to improve a numerical simulation method for turbulent bubbly flows.
