... that the numerical simulation of cavitation vortex and velocity field is in good agreement with the experimental data, illuminating the characteristics of energy performance, flow pattern, cavitation flow, broadband noise source, and near-field and far-field radiated noise. Compared with the original NACA0009...

... of the nozzle exit. Particular emphasis is placed upon the distinctive attributes of such a region. Both mean flow pattern and turbulent features are obtained statistically based upon instantaneous velocity data. The central region is overwhelmingly dominated by uniformly distributed velocity, and remarkably...

...Ali Benhmidene; Bechir Chaouachi; Mahmoud Bourouis; Slimane Gabsi In the present study, the ammonia-water mixing flow in a bubble pump is numerically simulated. The flow patterns of a two-phase flow in a bubble pump were studied under different conditions of heat flux and tube diameter. A one...

...S. Ghosh; G. Das; P. K. Das In the present paper, the pressure drop characteristics and flow patterns during downward vertical flow of lube oil-water as well as kerosene-water through a circular glass conduit have been studied. Core-annular flow has been observed to be the dominant flow pattern...

.... The results reveal that air enters the clearance at a critical rotational speed, which causes the drag torque to sharply decrease. The aeration mode and flow pattern are obtained via simulations. The rotational speed of the separator plate has a significant effect on the aeration, including the speed...

... and the pitching motions. In this paper, braking effects are investigated experimentally. It is found that the breaking effect is improved when the ratio of pitch to flap motions is large. Also, the flow pattern around the wind turbine is investigated. It is found that the braking effects are caused by a couple...
