...-phase flows are still very hard to predict depending on the case. Experimental studies remain very expensive to carry out and computational fluid dynamics (CFD) still struggles with two-phase flow prediction especially when a sharp interface between the two phases must be modeled. CFD is used to predict...

... given in this paper is to present a method that identifies the motion of foreign particles within an internal ribbed passage. The method uses a high-resolution, flow field interrogation method known as time-resolved digital particle image velocimetry (TRDPIV). Observations from the two-phase flows...

... (stoppers) two-phase flow In order to improve the thermal cycle efficiency of gas turbines, turbine entry temperatures have been continuously increased over the past decades. With these increases the ingestion of hot gases into the disk cavities has become an issue, as it can cause overheating...

... models assumed annular two-phase flows and were applied on the vent flows. Additionally, the two-phase flow in the scavenge and vent pipes was simulated numerically using the ANSYS CFX package. The evaluation of the models was accomplished with test data from the heavily instrumented test engine...

.... The experimental analysis provides measurements of pressure and torque as well as flow visualization. The numerical analysis is performed with the F LUENT code using the two-phase flow volume of fluid method. The results present a good consistency with experimental data. In particular, the pressure distribution...

...Yasushi Tatebayashi; Kazuhiro Tanaka; Toshio Kobayashi The authors have been investigating the various characteristics of screw-type centrifugal pumps, such as pressure fluctuations in impellers, flow patterns in volute casings, and pump performance in air-water two-phase flow conditions.
