Abstract

Recently, Computational fluid dynamics (CFD) software has become easy to use, fast and user-friendly. This new generation software offers an inexpensive means of testing and optimizing hydraulic operation of both existing constructions and those under design. In the present case, FLUENT CFD software was used to form an understanding of a periodic dysfunction at a drinking water production plant at a site in North Africa. The structure involved is a circular, 27-metre diameter, flocculator-settling tank, supplied with surface water taken from the nearby river. The following dysfunction was observed on the structure in question. In summer, during the hottest time of the day, a cloud of floes
