Being Sure About Surges - Focus on Safe and Reliable Systems Design

Transients flows in pipe/channel systems and components can have significant implications for their safe design and operation. This is important to avoid contamination of the environment or of the fluid being transported. Transient flow simulation and analysis is an essential requirement for assuring the safety and safe operation of pipework systems. It has been shown to improve the availability and reliability of pipework with considerable savings in maintenance, repair and liability costs. User-friendly software is available to assist engineers in many aspects of the field, but users should properly understand the physical process involved and the wide range of problems that can occur. They can then make informed interpretations of output. Without this know-how projects may proceed with a false sense of security and consequent risk.

The Conference will dealt with all aspects of unsteady flow and fluid transients in a variety of industries covering Energy and Power, Oil, Gas Chemical, Process and Petrochemical, Water Supply, Building Services and Utilities Systems and other industries.
