Abstract: A two-dimensional (2D) depth-averaged model of turbulent flows has been developed in a boundary-fitted curvilinear coordinate system. Based on the finite-volume method (FVM), the convection terms are discretized by the ...

Abstract: A mathematical model of three-dimensional (3D) free surface flows has been applied to simulate the curved channel flows and mass transport. In the horizontal plane, a channel-fitted curvilinear coordinate system is used, ...

Abstract: A drift‐flux formulation that accounts for multiple bubble interactions is applied to describe the mean water velocity, air fraction, and plume growth for a vertical air diffuser plume that is bound on one side. A coarse‐bubble ...

Abstract: The effects of the inlet densimetric Froude number on the velocity and suspended solids concentration fields in secondary circular clarifiers are investigated by application of a verified numerical model. The model consists ...

Abstract: The unsteady flow regime and the temperature mixing in temperature‐stratified settling tanks associated with a warm influent are investigated by application of a numerical model with two different turbulence models. The ...
