The mean and turbulent flow characteristics of a vertical slot fish pass, with without brush blocks, were investigated at the Cataloluk Small Hydropower Plant on Tekir River, located in Ceyhan River Basin Turkey. Within scope project, three-dimensional velocity measurements performed different hydraulic conditions. prototype showed that by placing blocks substrate vertical-slot pool: (i) maximu...

In this paper, synthetic jet actuators (SJAs) with three different orifice shapes (circular, square, and slot) the same cross-section area were investigated. The SJA efficiency (SJ) Reynolds number calculated based on time-mean reaction force measurement. momentum velocity was measured hot-wire anemometry additionally, sound pressure level (SPL) measured. equal maximally to 5.3% for each shape,...

Abstract Nozzles are widely used to control the rate of flow, speed, direction, mass, shape and pressure stream in connection with many different engineering applications. This paper presents performance predicted by a computational fluid dynamic (CFD) model, which 3D models that utilize parametric analysis, realizable k-epsilon turbulence experimental measurement for jet. Jet flows ejected fro...

Meteosat infra-red imagery for the Great Storm of October 1987 is analysed to show a series of very shallow arc-shaped and smaller chevron-shaped cloud features that were associated with damaging surface winds in the dry-slot region of this extra-tropical cyclone. Hypotheses are presented that attribute these low-level cloud features to boundary-layer convergence lines ahead of wind maxima asso...

Abstract In recent years, fluidic oscillators have been actively applied as devices for flow control in the field of aero and hydrodynamics. This study aims to investigate structure a sweeping jet ejected from oscillator into confined area – slot channel. Dynamics are investigated using PIV method with high temporal resolution. The effect Re number on oscillation frequency was studied range 1 5...

Following the footsteps of SemEval-2014 Task 4 (Pontiki et al., 2014), SemEval-2015 too had a task dedicated to aspect-level sentiment analysis (Pontiki et al., 2015), which saw participation from over 25 teams. In Aspectbased Sentiment Analysis, the aim is to identify the aspects of entities and the sentiment expressed for each aspect. In this paper, we present a detailed description of our sy...
