The Microcomputer and Pipeline Transients
Publication: Journal of Hydraulic Engineering
Volume 109, Issue 12
Abstract
A number of concepts related to computer studies of transient flow in pipeline systems are addressed. The topics are directed to applications on microcomputers, but are not limited to that special purpose. The topics include organizational concepts for system data handling, and ideas to realize certain storage and computational efficiencies when using the method of characteristics as the computational procedure. Alternatives to the method of specified time intervals, namely a staggered grid and an algebraic treatment, are discussed. A simple improved modification in the friction term is also emphasized. Two common elements in hydraulic systems that influence the form of pressure waves, series connections and lossy elements, are focused upon with a view to providing an improved visualization of their response characteristics. Equations and graphs are presented for cases with and without initial through flow. Finally, an example of the failure of a physical system is presented to emphasize the importance of unsteady flow visualization in hydraulic system design.
