Fluidic networks: Understand Failures and Optimize Equipment

Presentation of different damages occurring on fluidic networks, the reasons of their occurring and the means to prevent them.

Detailed description:

  1. Failure analysis & fluidic networks: Most of failures encountered on fluid   systems are the consequence of a wrong component sizing at design stage. In such a case, analysis of the ruptured component is not sufficient; a global system approach is necessary. The matter is illustrated through water hammer problem and a couple of case studies.
  2. Assemblies “The importance of the correct sizing and the quality of the construction for the good behavior of the networks”
  3. Detection of cavitation “Implementation of a system by non-intrusive method (PVDF)”
