Algorithm with improved accuracy for real-time measurement of flow rate in open channel systems
Agu, Cornelius Emeka; Hjulstad, Åsmund; Elseth, Geir; Lie, Bernt (Journal article; Peer reviewed, 2017)Most methods for flow rate measurement in open channels usually have low accuracy over a range of flow rates due to varying fluid properties, flow conditions and channel length. This paper suggests an algorithm to improve ... -
Numerical solution of the Saint Venant equation for Non-Newtonian fluid
Agu, Cornelius Emeka; Lie, Bernt (Journal article; Peer reviewed, 2014)Non-Newtonian fluid flow through a Venturi channel is studied using the Saint Venant equation. The nonlinear hyperbolic equation is numerically tricky to solve, therefore in this study, we consider the finite volume method ... -
Simulation of Transcritical Flow in Hydraulic Structures
Agu, Cornelius Emeka; Lie, Bernt; Elseth, Geir (Journal article; Peer reviewed, 2015-11-25)In hydraulic engineering, transcritical flows are often required in some applications. One example is in a Venturi channel where the occurrence of critical depth is used to estimate flow rate in the channel. In this paper, ...
