Hydraulic model study of turbulent flow measurement in sewer pipes conjunction

Abstract

This paper presents capabilities and benefits of use of physical models for flow analysis in large sewer pipes and conjoining objects. A group of objects pertaining to the Belgrade Sewer System is modeled and results are briefly discussed. The results show that the study of flow characteristics in sewer pipes and conjoining objects on the model can be done with a high level of confidence. Special attention has been drawn to the role of physical models in 3-dimensional flow investigation in nonstandard and objects of great complexity. Also, a physical model is introduced as a reliable and straightforward tool in decision making in positioning of future measuring points in Belgrade Sewer System. .

U radu su prezentovane mogućnosti i prednosti primene modelskih ispitivanja u analizi tečenja u velikim kanalizacionim kolektorima opšteg sistema kanalisanja. Na primeru objekata koji funkcionišu u sastavu beogradskog kanalizacionog sistema, prikazano je kako se na modelu, sa velikim stepenom pouzdanosti mogu izučavati karakteristike toka u kanalizacionim kolektorima i njihovim spojevima. Posebno je istaknuta uloga modelskih ispitivanja prostornih tečenja u objektima složene geometrije. Takođe, model je predstavljen i kao veoma pouzdano i očigledno sredstvo za davanje predloga o položaju budućih mernih mesta u beogradskoj kanalizaciji. .
