Abstract

High residence time due to dead-zones in fluid flow can appear in many engineering application and may cause severe water quality problems. Dead-zones can be eliminated only if their locations are known well. In this paper three different methods of deadzone detection are described and compared, particularly the coherent structure concept. This approach is based on the velocity gradient tensor of fluid flow, which is pre-calculated with the tool of computational fluid dynamics. The method was applied in a channel flow with a sediment trap and in a small swimming pool.
