Flow Structures in Vertical Solid-liquid Two-phase Flow under Microgravity Environment

A method for bubble volume measurement under constant flow conditions in gas–liquid two-phase flow

Measuring the volume of a bubble, especially at its detachment, is a basic subject in gas-liquid two-phase flow research. A new indirect method for this measurement under constant flow conditions is presented. An electronic device is designed and constructed based on laser beam intensity. This device calculates the frequency of the bubble formation by measuring the total time of the formation p...

Flow Pattern and Oil Holdup Prediction in Vertical Oil–Water Two–Phase Flow Using Pressure Fluctuation Signal

In this work, the feasibility of flow pattern and oil hold up the prediction for vertical upward oil–water two–phase flow using pressure fluctuation signals was experimentally investigated. Water and diesel fuel were selected as immiscible liquids. Oil hold up was measured by Quick Closing Valve (QCV) technique, and five flow patterns were identified using high-speed photo...

Large Eddy Simulation of Particle-Laden Flow by Using Solid / Liquid Two-Phase Flow Model

Achievement of a good performance in a Direct Numerical Simulation (DNS) of a particulate flow has been restricted to a low particle Reynolds number below a few hundreds due to the limitation of computational load by using a fine grid (Harada and Gotoh, 2008). Hence, in this study, to perform numerical simulations in higher particle Reynolds numbers, a Large Eddy Simulation (LES) by Smagorinsky...
