12th International Conference on Compressors and their Systems

Posted on August 31, 2021

PDM Analysis proudly sponsors the upcoming 3-day online 12th International Conference on Compressors and their Systems to be held on 6th- 8th September 2021 organised by the Centre for Compressor Technology at City, University of London.


Over the three days, delegates will participate in a forum for developments in air, gas and refrigeration compressors, vacuum pumps, expanders. The programme is more cohesive this year by including industry sessions on high-importance topics and the traditional keynote addresses, research and technical papers, podium papers, and discussions.


Short Course

The Conference will be followed by a Short Course and Forum on Computation Fluid Dynamics in Rotary Positive Displacement Machines, taking place on 9th – 10th September 2021, which will be run as a virtual-only event. More information


The forum will provide test results of dry air and oil injected twin screw compressors, a roots-blower, a dry air single screw expander and an ORC vane expander data for benchmark studies.


This short course/forum will bring benefits to engineers, engineering managers and specialists from industry, students, researchers and educators from academia and anyone who is interested in the modelling and design of rotary positive displacement machines.


Sponsor Area

There will be many exciting talks and presentations, and although the Conference will be held online this year, we will still be able to engage with you through the virtual exhibition! In addition, we are excited to showcase our latest developments of the software SCORG and our most advanced cloud solution, SCORG alto.
