The 2021 edition is part of a series of biennial conferences starting in 1999 from a collaboration between City and the Fluid Machinery Group of the Institution of Mechanical Engineers (IMechE).

City, University of London virtually hosted the 12th International Conference on Compressors and their Systems from September 6th to 8th 2021, followed by the 5th Short Course/Forum on Computational Fluid Dynamics (CFD) in positive displacement rotating machines on September 9th and 10th.

193 delegates from 24 countries attended the main conference and 49 delegates were present for the Short Course.

The conference was organised in collaboration with the Institution of Mechanical Engineers (IMechE), the Institute of Refrigeration (IOR), and the International Institute of Refrigeration (IIR) and two new partners, the Manufacturing Technologies Association (MTA) and Machines, an open access journal published by the Multidisciplinary Digital Publishing Institute (MDPI). The event was sponsored by Holroyd PTG, Howden, Fetu, Gamma Technologies, PDM Analysis and Megger and Victrex.

The biennial series of compressor conferences began in 1999 as a result of a collaborative effort between City and the Fluid Machinery Group of the Institution of Mechanical Engineers (IMechE), aimed at bringing together researchers, academics and professionals in the field of compressors and their systems from across the globe. The theme of this year’s conference was sustainability.

The theme of this year’s conference was sustainability.

In the first keynote address, Professor Ian Arbon drew on his decades of international experience in the compressor industry and in sustainable development, renewable energy and climate change mitigation/adaptation, to define sustainability.

On the second day, Dr Andy Pearson presented a keynote address on the challenges facing compressors in heat pump applications, while Professor Ruzhu Wang spoke about the role of heat pumps in meeting the Carbon Neutral Target.

The third day keynote address focused on compressors and industrial digitisation and was delivered by Dr Billy Milligan of Howden.

Social responsibility is an extremely important issue for a sustainable future. In his talk titled “The Engineer in Society”, Dr Colin Brown, former Chief Executive Officer of IMechE, reflected on the multiple perceptions that engineering generates, including its ability to do harm and good.

During the conference, the Best Paper Award went to Brijeshkumar Patel, Ahmed Kovacevic, and Aleksander Krupa for their paper, “A novel experiemental setup to measure velocity and temperature field in leakage flows of oil free rotary positive displacement machines”.

The Best Student Presentation Award went to Sumit J Patil, Nikola Stosic, Ahmed Kovacevic, Neeraj Asati and Ian Smith for “Application of Path Homotopy in Twin Screw Compressor Rotor Profile Design.”

The Best Student Paper award went to Heiko Pleskun, Timo Junemann, Tobias Bode and Andreas Brummer for “Modelling of inhomogeneous chamber states in rotary positive displacement vacuum pumps.”
