Abstract: Gas flow over ducted cavities can excite strong acoustic resonances within the confined volumes housing the cavities. When the wavelength of the resonant acoustic modes is comparable with, or smaller than, the cavity ...

Abstract: Flow over ducted cavities can lead to strong resonances of the trapped acoustic modes due to the presence of the cavity within the duct. Aly and Ziada (2010, “FlowExcited Resonance of Trapped Modes of Ducted Shallow ...

Abstract: Experimental and analytical study of an innovative strengthening system for deep corrugated structural plates (381-mm pitch by 140-mm depth) is described. A typical 7.94-mm thick deep corrugated structural plate can normally ...

Abstract: Scour at a bridge pier is the formation of a hole around the pier due to the erosion of soil by flowing water; this hole in the soil reduces the carrying capacity of the foundation and the pier. Excessive scour can cause ...

Abstract: This paper presents the design and experimental results of a new micro gas turbine architecture exploiting counterflow within a single supersonic rotor. This new architecture, called the supersonic rimrotor gas turbine ...

Abstract: Mesoscale weather systems that develop in the central United States are often forced by environmental features that have formed far upstream over the conventional data-sparse Pacific Ocean. Although remotely sensed ...

Abstract: Pretensioned concrete girders—especially those having large prestress forces—are susceptible to flexural cracking at their top flanges near the girder end as a result of prestress transfer. One effective method to reduce ...
