This research was conducted to find a reliable technique to shape an abrupt contraction for minimizing the energy loss. The method may find broader applications in design of variety of transitional cross-sections in hydraulic structures. The streamlines in a 2-D contraction were calculated through solving the potential flow equations in rectangular and curvilinear coordinates. The natural cubic...

The present study considers of the water and air flow and Micro-Bubble production inside the venturi tube, by the use of dimensional analysis. Numerical analysis of Micro-Bubble creation in venturi tube requires fast computers and large amounts of storage space. Up to now, there has been no numerical analysis concerning Micro-Bubble creation and all other existing studies are experimental. To s...

Abstract Wave energy converters (WECs) are built to extract wave energy. However, this kind of device is still expensive for commercial utilization. To cut down the cost WECs by sharing construction with breakwaters, an integrated cylindrical WEC-type breakwater system that includes a WEC array in front very long proposed and attenuate incident waves. This paper aims optimize performance system...

Oscillating water column (OWC) is an advanced form of wave energy converter (WEC). This study aims at improving the efficiency amended OWC through a novel methodology for simulating several vertical plates within chamber. paper provides numerical investigation considering one, two, three, and four plates. The open field operation manipulation (OpenFOAM) solver verified based on Reynolds-Average...
