Compressor surge can result in anything from minor seal rubs causing mechanical wear to catastrophic failure resulting in collateral damage. Compressor vendors and operators are taking every possible measure to prevent and avoid compressor surge, however there are many compressors that either operate in a region of close proximity to surge, or in surge.

The objective of the presentation is to:

  • establish a basic understanding of the physical phenomenon of surge;
  • highlight the process and operational circumstances under which surge can occur;
  • explain the causes of surge and its effect on compressor aerodynamics and performance;
  • suggest ways of avoiding and mitigating against surge;
  • demonstrate the importance of compressor surge mapping, the effect of operating conditions on the surge control line and effective available surge safety margins;
  • compressor dynamic simulation and the sizing of anti-surge control valves.

The aerodynamics of surge will be presented in a way that cannot be found in any text book or technical paper with real life examples and interesting case studies.

The presenter

Arun Karuppasamy is a rotating machinery consultant at g3baxi partnership (UK) Dorking office. His expertise includes design and development of turbomachinery, specialising in compressors and gas turbines for upstream oil and gas business. He holds a masters degree in aeronautical engineering from the Indian Institute of Technology, Kanpur.
