Surge Short Course Presented at ASCE/EWRI World Enviromental & Water Resources Congress

ASCE/EWRI World Enviromental & Water Resources Congress
Austin, Texas – May 21, 2015
Course: Effective Surge Protection – Going Beyond Modeling Tools
Presented by: Dr. Srinivasa Lingireddy
 
Short Course Description:
With more than 300,000 water main breaks each year in North America alone, it is no surprise that more water utilities are gearing towards comprehensive transient modeling of their pipeline infrastructure. Though this was inconceivable a few years ago, the advent of high speed computing coupled with Lagrangian-based unsteady flow modeling tools is allowing for designing efficient surge protection systems even for very large water distribution systems. While sophisticated modeling tools help build and analyze transient network models with ease, a prudent designer needs to go well beyond modeling tools for arriving at an efficient and robust surge protection system. This short course is aimed unraveling the relationships between surge protection methods and surge protection equipment along with an in depth discussion on limitations of mathematical models and critical analysis of the results. The presentation will draw from more than two decades of experience encompassing research and development of modeling tools, designing and commissioning of surge protection systems, and close working relationships with surge protection equipment manufactures. Several real case studies from around the world will be embedded into the presentation.
Learning Objectives:

  • Understand the limitations of modeling tools for transient analysis of pipe systems
  • Identify the data constraints
  • Relate functional aspects of surge protection devices with the associated surge protection methods
  • Appreciate the power of Lagrangian-based modeling tools for transient analysis
  • Understand the relative merits of different surge protection methods and equipment
Outline:

  • Causes and effects of hydraulics transients in pipeline systems
  • Modeling tools – brief overview of Lagrangian Method and its computational power
  • Methods for mitigating pressure surgess
  • Surge protection equipment – flywheels to bladder vessels
  • Case Studies
  • Best Modeling Practices
