This book provides details on surge modeling in general and the use of WPM in particular. This includes pressure attenuation, determination of wave speeds in different pipe types and various liquid media, pump and turbine characteristics curves, and the effects of boundary conditions. The discussion of boundary conditions includes an extensive look at the effects of the air-water interface as it applies to bulk air intrusion into pipelines, and as it relates to the use of air/vacuum valves as surge protection. The authors discuss surge protection design for different real-world scenarios, and how to model of a full list of surge control devices, including a detailed discussion of check valves. Last, the book describes the assumptions and uncertainties encountered during data collection and model building, and examines the potential effect of these uncertainties. Where uncertainties cannot be mitigated, the authors discuss ways to increase the safety factor of surge protection designs.
Dr. Srinivasa Lingireddy has held the position of associate professor of Civil Engineering at the University of Kentucky and has over 20 years of experience in pipe network modeling and is extensively published in this and other related areas. He has over 30 papers in reputed technical journals and countless other technical papers, reports and chapters in various textbooks. He has received national awards for his work on hydraulic modeling and has provided technical consulting services for scores of top engineering firms worldwide.
Don J. Wood is a Professor Emeritus of Civil Engineering at the University of Kentucky and currently the CEO of KYPIPE, LLC. He received the Ph.D. from Carnegie Mellon University and is the author of over 110 technical papers dealing with steady-state and transient flow. He is a co-author of the AWWA Engineering Division 2007 best paper – AWWA Journal, titled, “The Need for Comprehensive Transient Analysis of Distribution Systems.” He received the 2004 Simon Freese Environmental Engineering Award and presented the award-winning lecture titled, “Waterhammer Analysis – Essential and Easy” at the 2004 EWRI Congress. He has received numerous other awards, including the national ASEE Western Electric Outstanding Engineering Professor and the ASCE Huber Research Prize in addition to many teaching awards such as and the Outstanding Engineering Professor and the Lutes Teaching Award. In March 2011, Dr. Wood was awarded the prestigious Honorary Diplomate, Water Resources Engineer (Hon.D.WRE) title. These awards were presented largely in recognition of his work in developing state-of-the-art techniques in pipe network flow modeling. Dr. Wood is the creator of the powerful node/loop method for steady-state pipe network analysis. He is the developer of the widely-used KYPipe program for steady-state flow and pressure analysis in large piping networks that carry water and other liquids. He is also the creator of the computationally-efficient and accurate wave method for analyzing transient flow and the principal developer of the widely-used Surge program for modeling transient liquid flow in piping systems. Both of these commercial software packages are used extensively worldwide. He is also the senior author of a recent text on transient pipe flow.
Dr. Wood has taught short courses on steady-state and transient pipe system modeling at numerous locations worldwide. He also is very active in consulting activities for engineering consulting firms in the area of transient flow including transient analysis of sprinkler systems. In addition Dr. Wood has developed the GoFlow software package for the analysis of fire protection sprinkler systems.
