Proc. ASME. FEDSM2021, Volume 3: Fluid Mechanics; Micro and Nano Fluid Dynamics; Multiphase Flow, V003T08A002, August 10–12, 2021
Paper No: FEDSM2021-65716
...Abstract Abstract Discrete bubbles can be effectively cracked and dispersed in a Venturi channel with its unique structural characteristics, and the general Venturi channel has been widely used in the practical engineering. Bubble breakup mechanisms based on Venturi channels have been...

Paper No: FEDSM2021-65627
... simulation in this study is the first simulation in the foam flow, in which both the bubbles and the water are simulated as two-phase flow. In this study, fluid containing a surfactant and bubbles are flowing in a duct. The dimensions of the duct cross section is 15 × 60 in millimeters. The numerical...

Paper No: AJKFluids2019-5252
...Abstract Abstract Inside an automobile engine, there are a camshaft, a crankshaft, a chain sprocket, etc. that transmit driving force. There are many rotating parts installed there. For example, there are gears soaking in engine oil, and bubbles are generated by rotating gears which drag air...

Paper No: FEDSM2002-31139
... 04 03 2009 The motion of gas bubbles in a liquid medium is known to be affected by the presence of surface active molecules which modify the hydrodynamic conditions prevailing at the gas-liquid interface. In the past, gas bubbles rising in aqueous solutions have been said to follow...

Paper No: FEDSM2006-98156
... 08 09 2008 A hybrid CMFD (computational multi-fluid dynamics) method is proposed for the prediction of multiphase flows including large-scale interface, poly-dispersed bubbles and/or drops. The method is the hybrid integration of an interface tracking method (ITM), three kinds...
