International Conference on Screw Machines 2018

Dear friends of the screw machines Welcome to the International Conference on Screw Machines 2018 (ICSM 2018). This worldwide unique conference with the exclusive focus on research and development of screw machines is now taking place for the 10th time at the TU Dortmund University. I am particularly pleased that this internationally orientated conference brings together authors and participants from 13 countries around the globe. This is a unique opportunity for the community to grow together, from young engineers to the “old hands”. My highly esteemed colleague Prof. Knut Kauder, who had been doing research in the field of screw machines since 1975, had the idea for the first conference (“Schraubenmaschinen ‘84”), which took place in 1984. I am particularly pleased that one of the speakers at the first conference and certainly a very well-known scientist in the field of screw machines, Prof. L. Rinder, is faithful to this conference and is present today. Another prominent representative of the developers of screw machines is Jack Sauls, who gave his first presentation at this conference in 1990 and is also present today. Despite these years of research and development, many scientific questions regarding screw machines are still unanswered today. These include, for example, the modelling or simulation of the multiphase flow, the potentials offered by new manufacturing possibilities of the rotors or the special challenges of designing screw spindle vacuum pumps. The 33 presentations and papers of the 10th ICSM deal with these questions and many other topics. The contributions of all nine previous conferences and the contributions of the 2018 conference are freely available and can be downloaded on the conference website (www. icsm.tu-dortmund.de). Additionally, the papers of the ICSM 2018 are published in the open access IOP (Institute of Physics) conference series. Finally, I would like to thank everyone involved for their pleasant and constructive cooperation. Firstly, the sponsors of the conference, PTG Holroyd and Kapp Niles, without whom the small conference fee would not have been possible. Furthermore I would like to thank the authors, who have put a lot of time and effort into preparing the papers. The program committee and the reviewers, who ensured the high scientific standard of the conference, are to be mentioned immediately afterwards. My very special thanks to the entire chair of fluidics team, who prepared and organized the conference with a lot of time and effort. From this group I would like to thank Mrs. I. Kokott and Mr. C. Huck personally for their above-average commitment and excellent organizational talent. Prof. Andreas Brümmer Conference Chair
