Hydraulic Modeling and Dynamic Open Flow Calibration

The following is a very useful article on hydraulic modeling of firewater sprinkler systems: Hydraulic Modeling and Dynamic Open Flow Calibration By Phil Smith, Project Manager and Chen-Hsiang Su, PE, Senior Consultant, Lincolnshire, IL, JENSEN HUGHES. The paragraph shown below summarizes the article: A hydraulic model is a computer program configured to simulate flows for a hydraulic system. The system …

Using Control Valves for Surge Protection

Suppose you need to shut down the flow in a pipeline in a specified period of time. This action will always cause a pressure surge related to the deceleration of the fluid in the pipeline. The type of valve you use and how it is operated can have a very significant effect on the magnitude of the pressure surge and …

Some Straight Talk about Transient Pipe Flow Analysis (MOC vs WCM)

By Dr. Don J. Wood and Dr. Srinivasa Lingireddy Back in the 1960’s pipe system transient analysis code using a technique developed by Dr. Wood was written to handle propellant flow transients for NASA. This technique, initially referred as the Wave Plan Method, was further developed and around 1984 the first commercial software (SURGE1) was released for general use. Since …

Sprinklers, Fire Flow, Landfill Gas, Low Pressure Sewers, etc.

Over the past 35 years we have had many, many excellent interactions with our users and potential users and they have stimulated us to develop many special capabilities. Here are a few examples: Rural Water Analysis – we have a module which will analyze water utility systems using the Peak Demand Curve. This curve gives the peak demand for each …

Vacuum Breakers and Hydrotanks

Here is my first blog ever. My associates tell me I have to get into the 21st century so here goes. We are creating lots of new and exciting developments in pipe system modeling.  We keep getting useful suggestions from users and the very close association we have with our users through our technical support activities constantly lead us to new …
