Sivakumar, M. & Lowe, S. A. (1990). Simulation of the Effect of Wind on Rectangular Sedimentation Tanks. Conference on Hydraulics in Civil Engineering, 1990 (pp. 74-78).


A numerical model is presented to simulate the effect of wind action on rectangular sedimentation tanks used in water and wastewater treatment plants. The mathematical model uses the k-r. model for fl uid flow and sediment transport, and is solved using an explicit finite diffence scheme incorporating a penalty function approach. Simulations of fluid flow velocity and aeqiment concentration are presented for two wind speeds in two directions. It is shown that the effect of wind action is significant and future design of sedimentation tanks should include this parameter.
