Transcription

1 Aeronautics Days, Vienna, Austria, June 19-21, 2006 A European collaboration on development, quality assessment, and standardisation of Particle Image Velocimetry for industrial applications Thematic network with 38 partners from Europe funded by EC

2 Principle of the PIV technique 2

3 Partners of PivNet 2 in Europe 3

4 Structure of PivNet 2 Partners Partners from sectors UNI = 16 NRC = 9 38 Partners SME = 4 IND = 9 A total budget of 1,5 mio funding was provided by EC for network activities from April 2002 to November 2006 (5 month elongation of the term) 4

5 Workpackage Description Structure of tasks 1 Coordination and general networking, knowledge base, gateway, and exploitation (all partners) 2 Exchange of information and know how with industry Workpackage manager DLR DLR 3 Presentation of PIV to industry AIRBUS 4 Quality and standards for PIV in TU Delft industry 5 Supporting new applications, VKI interaction with manufacturers of PIV systems and SME s, training 6 Further assessment of PIV technique, ERCOFTAC SIG 32 and internl. PIV challenge LML(CNRS) 5

6 Main Objectives of PivNet 2 4 to establish direct information exchange between end users in industry and PIV developers in universities and research institutes in order that the end users will obtain a clear picture of the state-ofthe-art of the PIV technique and the developer will receive knowledge about problems in industry to be solved with PIV 4 to demonstrate the applicability of PIV for investigation of complex flow fields by performing state-of-the art presentations in industrial facilities (transonic wind tunnel, catapult tunnel, icing wind tunnel, large water towing tank, turbomachinery test rig...) 4 to spread the knowledge and experience on PIV as gained in the area of aerodynamics during the past 15 years to other fields of industrial, economical and ecological interest: combustion, naval field, environmental flows, house-hold appliances, medical field 6

7 Workshops and Presentations More than 22 workshops dedicated to special (industrial) applications of PIV and/or aspects of adaptations and development Demonstrations of PIV applications in industrial facilities, test rigs and laboratory have been performed in many related presentations More than 800 participants from research and industry have been registered during all workshops Database of events, reports and scientific presentations available for all Partners at 7

8 Main thematic fields of Workshops 4 Bio-medical applications 4 Wake vortex investigations 4 Comparison with and validation of CFD 4 Household appliances 4 Two-phase flows and icing problems 4 Assessment of PIV hardand software 4 Naval applications 4 Supersonic flows 4 Turbo machinery 4 Internal combustion 4 Car industry 4 Complex aerodynamics 4 Main results of PIV challenges 4 3D-PIV 4 µpiv and applications to micro systems (lab on a chip) 8

9 Workshop and Presentation example 1 PIV for wake vortex investigations Within frame of AWIATOR 9

10 Workshop and Presentation example 2 PIV for complex aerodynamics 10

11 Workshop and Presentation example 2 PIV for complex aerodynamics With clean strake Within framework EUROLIFT 2 11

12 Example 3: PIV Challenges A competition on evaluation codes 12

13 Most recent development: 3D(t) PIV 13

14 PivNet 2 A beneficial network for the development of advanced measurement techniques for industry and research 4 The application of PIV in aerodynamic research and in different fields of technical flows provides huge data sets of quantitative information about unsteady flow phenomena. This gives a deeper insight into the governing physics and became an important tool for the assessment of flow control devices 4 PIV covers the need for data to validate Computational Fluid Dynamics (CFD) codes as the main design tools in modern (aviation) industry 4 The network enables work share and the collaboration accelerates the development of the technique itself and the dissemination of knowledge into different fields of technical flows and aerodynamics 4 The EC funded network produces outputs which strongly supports research and development especially for the European aviation industry, which would not have been achieved otherwise 14

15 4The PivNet2 network run time will end in November Final Workshop will take place at DLR in Göttingen on September 7-8, 2006 linked to the 12th International Symposium on Flow Visualization (ISFV) on September At the end a book with scientific papers from all thematic research fields will be compiled within the Springer book series Topic of Applied Physics 15
