Návrhové parametry a výstupy modelové studie tangenciálního spadiště s vysokým spádem

Original language description

The presented study is focused, similarly to previous work of the authors, on theoretical consideration and experimental work on the drop shafts with high hydraulic drop. Within the planning of new vertical drop shaft in Prague catchment the authors present latest results and findings at circular drop shaft with tangential vortex inlet. The results show that stable vortex structure with air core along the whole depth of the drop shaft can be created over the full range of flow conditions. This has a positive effect on energy attenuation using vortex structure and wall friction, and simultaneously accompanied with low water aeration. The mentioned positive effects enable to reduce the length of attenuation chamber and improve the flow conditions in outlet sewer section. Next to the study presents non-traditional design of foul sewage bypass including bottom opening structure
