CMFF is a historical international conference series, formerly known as Conference on Fluid Machinery, and held every fourth year in Budapest since 1959.

The recent focus of the conference is the coexistence of and collaboration between numerical flow simulation and physical flow modelling using advanced measurement methods.

The main thematic areas of the Conference Series are as follows:

Each thematic area covers research, development, design, new applications and equipment, case studies and future trends with particular emphasis on the use of CFD and advanced measurement methods.

The deadline for abstract submission is10th January 2022for those who have been informed about the event through ERCOFTAC. During the abstract submission process, please include #ERCOFTAC in the list of keywords.

You can find more information about the event on the conference website at www.cmff.hu

Links of the Conference Organizers to ERCOFTAC

There are strong links between ERCOFTAC and the organizers of CMFF, outlined as follows.

• The Organizer of CMFF is Department of Fluid Mechanics (DFM), Faculty of Mechanical Engineering, Budapest University of Technology and Economics. DFM is a long-term ERCOFTAC institutional Research Member. The head of DFM, Prof. Janos VAD, is the chairman of the Local Organizing Committee of CMFF.

• Professor Dominique THEVENIN is the Chairman of the International Scientific and Programme Committee of CMFF. The institution headed by Professor Thevenin is the Laboratory of Fluid Dynamics and Technical Flows; Otto-von-Guericke Universitat Magdeburg,Germany. The institution is a Co-Organizing Association of CMFF, as well as a long-term ERCOFTAC institutional Research Member. They have organized several summer-schools with ERCOFTAC support.

• Under the coordination of Dr. Gergely KRISTOF, shared the coordination with other professors, DFM has been undertaking a substantial contribution to the activity of the ERCOFTAC Alpe Danube Adria Pilot Centre (ADA PC) since 2005. DFM regularly contributes to the technical programmes of these ERCOFTAC events.

• Meetings of the aforementioned Pilot Centre were organized by DFM in Budapest in 2006, 2010, and 2013.

• The 2009 ERCOFTAC ADA PC Spring Festival ,,Pantha Rei" was hosted by DFM in Budapest. The CMFF event held in that year (CMFF'09) was popularized among the ERCOFTAC representatives at the Festival.

Conference History

The success of CMFF'03 in 2003 (170 presenting authors from about 30 countries), coupled with the rapid development of fluid mechanics, encouraged the Conference Organizers to increase the frequency of the events to every third year. The subsequent events CMFF'06, CMFF'09, CMFF'12, and CMFF'15, held in 2006, 2009, 2012, 2015, as well as in 2018, maintained the level of participation and internationality of the previous conference.
