Applied Research: Hydraulic Transients

Primary investigators: Arturo S. León and Arthur R. Schmidt.

Abstract

A two-phase flow model (air-water) named ILLINOIS TRANSIENT is being developed for the unsteady analysis of free surface, pressurized and simultaneous occurrence of open channel and pressurized flows termed mixed flows. The ILLINOIS TRANSIENT program is being designed to analyze complex hydraulic systems including several boundary conditions such as dropshafts with and without hydrographs, reservoirs, junctions, pumping stations, air chambers, etc. This research is part of the second phase of the TARP project and its ultimate goal is a real-time flow model for the operation of the TARP system in Chicago, Illinois (USA).
