Abstract: A numerical and analytical investigation is performed on a dissolved air flotation (DAF) pilot tank by using the residence time distribution (RTD) of the conservative dye rhodamine measured with a fluorometer. The experiments ...

Abstract: The effect of hydraulic transients on water and sewage pipes is studied by measuring the pressure and the strain in pipes simultaneously during field conditions. Both the axial and circumferential strains were recorded for ...

Abstract: A model that describes the density-profile evolution in a confined region with a stably stratified fluid, where mixing is induced by a circular, nonswirling turbulent jet discharged vertically down into the fluid is presented ...

Abstract: The velocity field downstream of a model impeller operating in water was measured using a two-component laser doppler velocimeter. The investigation focussed on the spatial development of the ...
