Vortex shedding from cylinders has been extensively studied due to its occurrence in many engineering fields. Many experimental studies reported in the literature focus on the aerodynamics of the vortex shedding process but the literature about the radiated noise is more scarce. The aim of the work presented here is to extend the available noise data. Aero-acoustic wind tunnel tests were carrie...

Continuous casting is used to mass produce basic metals into long, semi-finished shapes with constant cross section, which are later processed into over 800 million tons of steel, 20 million tons of aluminum, and 1 million tons of copper, nickel, and other metal products in the world each year. Cross-sections can be rectangular, for later rolling into plate or sheet, square for long products, c...

Most of previous works for discharge measurement structures were carried out in canals with rectangular cross sections. However, in irrigation systems most common irrigation canals, especially lined canals, have trapezoidal cross sections. From practical view point, it is preferable to construct measuring structures without changing the side slopes of the original canals. Usually, a horizontal ...

In this study, the scour depth and dimensions of hole around different shaped piers for cases hydrographs succeeding steady flow were studied experimentally. The experiments carried out by using circular, square, rectangular, lenticular rectangular with trapezoidal nose to compare various geometries at same conditions. Numerous conducted in a flume (18.6 m long, 0.80 wide 0.75 deep) triangular ...

Different fields and disciplines in Science and Technology are imposing more stringent and accurate measurements of the proton and neutron total and differential cross-sections in the intermediate-energy range, from a few dozens of MeV up to a few GeV. Such measurements could be performed in facilities disposing of proton or light ion beams (namely facilities to produce Radioactive Nuclear Beam...
