Solute Mixing Models for Water-Distribution Pipe Networks

摘要: The spreading of solutes or contaminants through water-distribution pipe networks is controlled largely by mixing at junctions where varying flow rates and concentrations can enter the junction. Alternative models solute within these are presented in this paper. Simple complete-mixing discussed along with rigorous computational-fluid-dynamics based on turbulent Navier–Stokes equations. In addition, a new model that describes bulk-mixing behavior resulting from different entering leaving junction developed Comparisons experimental data have confirmed provides lower bound to amount occur junction, while yields an upper bound. simple scaling parameter used estimate actual (intermediate) bounding predictions models. These analy...
