Abstract: This paper presents a simple graphical technique for studying the hydraulics of two-layer inviscid flows with a hydrostatic pressure distribution. A control curve, which relates the internal energy with the flow rate, is ...

Abstract: This study experimentally investigated the axis switching of free-falling water jets issued from an elliptical nozzle with an aspect ratio of 1.6. High-speed photography was used to capture the flow behaviors. The ...

Abstract: Hydrogen sulfide (H2S) is the primary cause of odor and corrosion in sewer systems. When wastewater breaks up into small droplets in drop structures, the emission of H2S is expected to be significantly enhanced relative ...

Abstract: Rapid filling of a horizontal pipe with an entrapped air pocket has attracted significant attention as overpressurization induced by air compression may cause safety concerns. This study developed a linearized model for a ...

Abstract: As sewer pipes age, groundwater and the surrounding soil can enter into the sewer system through various defects on the pipe wall. Groundwater infiltration and soil erosion through cracked sewer pipes can result in increased ...

Abstract: Transverse mixing in an unregulated northern river in Canada was studied in different discharge conditions with and without ice cover. The distribution of cumulative discharge was constructed on the basis of river ...

Abstract: An experimental study was conducted to investigate the use of a temperature-control curtain in selective withdrawal from a two-layer stratified reservoir. This study focused on the case where cool water at a depth was ...

Abstract: Trajectories of bubbly jets in crossflows by injecting air-water mixtures vertically through a circular nozzle were experimentally studied. Bubbles separated from the water jets in strong crossflow, similarly to that of ...

Abstract: Near-field mixing downstream of a multiport diffuser in a wide shallow river was studied with a field dye test. Dye concentrations at different depths and lateral locations were measured. The near-field mixing was analyzed ...
