With a strong participation from the compressor industry, CFD software providers, and academia, this 4th short course/forum (https://www.city.ac.uk/compressorsconference/short-course-on-compressors) is dedicated to advanced topics of modelling, analysis, and the design of Positive Displacement Machines for industrial and research use.

The main topics include, but are not limited to the following:

* Advances in grid generation, CFD tools, and new techniques for PD machine analysis.

* Modelling of leakage flows and conjugate heat transfer.

* Prediction of clearance gap sizes during operation and the application of modern FSI computations.

* The stability and accuracy of multiphase flow calculations in PD machines.

Participants from academia and industry are invited to prepare journal publications with results from their research and analysis and present them in the forum.

The papers presented in this Short Course will be published in the special Issue on "Modelling, Analysis, and Design of Positive Displacement Machines” of journal Designs, published by MDPI.

This Special Issue and the short course/forum will be of interest to engineers; engineering managers and specialists from industry; students, researchers, and educators from academia; and anyone who is interested in modelling and design of rotary Positive Displacement Machines. It will be prepared and presented by leading scientists and researchers from industry and academia, and will provide insight into new technologies and the state of the art in modelling Positive Displacement Machines.

This short course and forum is organised by the Centre for Compressor Technology at City, University of London.
