Designing Manhole in Water Transmission Lines Using Flow3D Numerical Model
Abstract: Using cascades and
drops existing in flow path has a history of 3000 years. Particularly, Roman
engineers employed stepped spillways with the same idea in several countries;
however, there are few information about the hydraulic performance of
aqueducts. Most of these channels have flat long cross sections with low
torsions (variable slope) such that they can encompass cascade and steep
spillways or dopshaft. Given that there are few studies conducted on
dropshafts, the present paper attempted to discuss about such structures in
flow path and water transmission lines as well as introducing the existing
principles and relations and present, the obtained results of designing though
Flow3D. The obtained error percentage was about 20% which is acceptable for numerical
studies.
