City, University of London hosted the 13th International Conference on Compressors and their Systems from September 11th to 13th 2023, preceded by the 6th Short Course/Forum on Computational Fluid Dynamics (CFD) in Rotary positive displacement machines, which took place on September 9th and 10th.

The theme of the Conference was Compressors and Expanders in Future Energy Systems.

234 delegates from 29 countries attended the main conference. The Short Course and Forum was attended by 55 delegates with 16 presentations made.

The conference was organised in collaboration with the Institution of Mechanical Engineers (IMechE), the Institute of Refrigeration (IOR), British Compressed Air Society (BCAS); the International Institute of Refrigeration (IIR); the European Forum for Reciprocating Compressors (EFRC); the Manufacturing Technologies Association (MTA); Open Access journal Machines; ANUBiH; Nineteen Group and the Lightyear Foundation. Holroyd was the Platinum Sponsor of the Conference while Howden was the Gold Sponsor. PDM Analysis, Jacklin Industrial, Kapp Niles and Mayekawa were Silver Sponsors and Megger was the Gala Dinner Sponsor.


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), which was aimed at bringing together researchers, academics and professionals in the field of compressors and their systems from across the globe.

In the first keynote address, Professor Ian Arbon drew on his wealth of international experience to address the issue of Hydrogen Compression Challenges for Net Zero Targets.

On the second day, Jin Yang spoke about a Low Carbon Heating Solution via Heat Recovery with Heat Pump.

The third day’s keynote address focused on 3D printing for compressor Design: Limitations and advantages, delivered by Kim Tiow Ooi.

756017 During the conference, the Best Paper Award went to Leon Philipp Martin Brendel,, Silvan N. Bernal, Dennis Roskosch, Cordin Arpagaus, Andre Bardow, and Stefan S. Bertsch, for their paper, Compressor performance for varying compositions of high-glide mixtures R1233zd(E)/R1234yf and R1336mzz(Z)/R1234yf.

The Best Student Paper Award went to Lukas Dür, Andreas Egger, Michael Lang, Raimund Almbauer, Ferdinand Cloos and Fabian Brugger, for their paper, Measured reed valve dynamics of diaphragm pumps with laser Doppler vibrometer.

The Best Student Presentation Award went to Abhishek Kumar, Kewal Patil, Amey Kulkarni and Sumit Patil for their paper, Investigating alternative rotor materials to increase displacement and efficiency of screw compressor while considering cost and manufacturability.

The 14th International Conference on Compressors and their Systems returns to City, University of London from September 8th to 10th 2025.
