... were varied systematically between 1 mPa · s (water) and 36 mPa · s (water-glycerol mixture). The implemented test matrix varied between 0 – 32 m/s for gas superficial velocity and 0.003 – 1.3 m/s for liquid superficial velocity respectively. The internal pipe diameter making up the junction is 5 mm...

... oscillating in a bubbly medium. (2) Method of approach. A coupled Eulerian-Lagrangian, a multicomponent compressible, and an analytical approach are compared for different void fractions. (3) Results. While the homogeneous mixture models (analytical and multicomponent) compare well with each other...

...Boštjan Gregorc; Matjaž Hriberšek; Andrej Predin The purpose of this paper is to present an analysis of the impact of solid particles on the development of cavitation flow conditions around a hydrofoil. Experimental studies were conducted in a cavitation tunnel with different mixtures of particles...

...E. Sansone; C. Pellone; T. Maitre The noncavitating and cavitating flows over a cross-flow water turbine are simulated by using an unsteady Navier–Stokes formulation. For the cavitating flow case, a homogeneous mixture with a varying density is considered and one additional transport equation...

... at the base of the wall. Far from the source, the resulting plume becomes self-similar to a good approximation. Several turbulence models based predominantly on the k - ε modeling technique, including algebraic stress modeling, are examined and evaluated against experimental data for the mean mixture fraction...

...F. Sanchez-Silva; V. Hernandez-Perez; I. Carvajal-Mariscal; J. G. Barbosa-Saldaña; J. A. Cruz-Maya Novel experimental data for phase separation of air-water mixtures in horizontal 90 deg branched elbows are presented in this work. The branched elbows were formed by attaching a pipe to a 90 deg...

... and discharges a two-phase mixture at the exit. In this work, a two-fluid model (TFM) is developed for modeling the flow characteristics of supercritical C O 2 through the short tube orifice. The deviations between the TFM predictions and the measured mass flow rates are within ± 20 % . Meanwhile, the TFM...

... the two-phase mixture as a homogeneous fluid under the design condition. The three-dimensional flow in the designed impeller is verified by direct turbulent flow analysis, and the design specification is further modified to optimize the flow distribution. A helical axial pump of high specific speed has...

...Philippe Guibert; William Perrard; Ce´line Morin The fuel concentration in a pressurized and heated gas mixture flow was measured by LIF (laser induced fluorescence) technique. Diacetyl was used as the fluorescence tracer of fuel and was excited at a wavelength of 355 nm. Influent parameters...

...Tahsin Engin, Assist. Professor; Mesut Gur, Professor This paper presents extensive results on the performance of an unshrouded centrifugal pump impeller handling solid-liquid mixtures. The effect of the clearance between the impeller tip and the casing and of the solid concentration, density...

...Vineet Ahuja, Research Scientist; Ashvin Hosangadi, Principal Scientist; Srinivasan Arunajatesan, Research Scientist A new multi-phase model for low speed gas/liquid mixtures is presented; it does not require ad-hoc closure models for the variation of mixture density with pressure and yields...
