Abstract: The main objectives of the present work were to investigate the flow field over a spillway and to simulate the flow by means of a three-dimensional (3D) numerical model. Depending on the wall curvature, the boundary layer ...

Abstract: Experimental study of clear water scouring around a circular cylinder shows that the scour mechanism is coupled to the three‐dimensional separation of the upstream boundary layer and the periodic vortex shedding in the ...

Abstract: The shear coefficient in Timoshenko beam theory is derived for thin-walled beams constructed of orthotropic laminated composite panels and new formulas for the common forms of thin-walled section are presented. The results ...

Abstract: This paper presents the results of hydrogen-bubble flow visualization and hot-film velocity measurements of the turbulent flow structure along a flat wall. The objectives of the study were to examine the interaction of the ...

Abstract: The field and laboratory data for wind shear stress coefficient at the air-water interface are reanalyzed. The major discrepancy between the field and laboratory data for wind shear stress coefficient is removed by adjusting ...

Abstract: Semiactive control systems combine the features of active and passive control to reduce the response of structures to various dynamic loadings. They include: (1) Active variable stiffness, where the stiffness of the structure ...

Abstract: Groups of cylinders can be found in many engineering fields such as marine and civil applications. The behavior of the group cylinders can be very complex because it undergoes the mutual effects of adjacent cylinders ...
