Abstract: Backwashing of deep bed filters is achieved by fluidizing the filter media. A mathematical model for velocity gradient in two‐dimensional turbulent flow that can also be applied to flow in fluidized beds in the transitional ...

Abstract: Cable-stayed bridges with long spans are excited by different support vibrations on both sides of the main span. Therefore, a realistic seismic structural analysis of the bridge must involve multiple-support excitation. ...

Abstract: The tuned mass damper (TMD) is one of the oldest and most widely used passive control devices, designed to absorb lateral energy from structures and mitigate vibrations. Various methods have been proposed for the optimal ...

Abstract: At Re=2000, the predicted flow field around a circular cylinder in forced transverse oscillation is verified with experimental results. For coupled torsional and transverse oscillation cases, the ...

Abstract: A modified k-ε model is proposed to predict complex, adverse pressure gradient, turbulent diffuser flows. The need for an eddy viscosity is eliminated by using three structural parameters. A ...

Abstract: Project managers play a critical role in the success of architectural-engineering firms. They have responsibilities that may begin before project acquisition and continue beyond project close-out. They also have responsibilities ...

Abstract: After the collapse of the Interstate 35W Bridge in Minneapolis, Minnesota, in 2007, transportation agencies began evaluating and rating their inventories of gusset plate connections. Connection evaluations require accurate ...

Abstract: Orthotropic plates are widely used in bridge deck systems. However, these are not commonly treated as such within design specifications, and semianalytical solutions are not presently available for all deck types. This ...

Abstract: The turbulent flow inside a low-speed centrifugal compressor at design condition is investigated using large-eddy simulation (LES) comprising of up to 26×106 computational volume cells. Unlike ...
