STVF Framwork Program: Computational and Experimental Fluid Mechanics
The framework program Computational and Experimental Fluid Mechanics (C&EFM) has been funded by the Danish Technical Research Council (STVF) during the 5-year period 1-1-93 to 31-12-97, beginning with 2.5 mioKr/year and increasing to 3.0 mioKr/year. It has been a collaborative research program amongst the following university partners:- Afd.for Fluid Mekanik (AFM), Inst.for Energiteknik (ET), DTU- Institut for Matematisk Modellering (IMM, formerly NI), DTU- OptikGruppen, Fysisk Institut (OG-FYS), DTU- Institut for Kemiteknik (KT), DTU- Institut for Skibs- og Havteknik (ISH), DTU- Institut for Strømningsmekanik og Vandbygning (ISVA), DTU - Institut for Energiteknik (IFE), AUC The aim of the program has been the development of efficient algorithms, their implementation in codes of Computational Fluid Mechanics (CFD), and the experimental verification of these codes. Flows of both fundamental and applied nature have been investigated, including flows in industrial process equipment, around aerodynamics structures and ships, and flows over bed forms of importance for sediment transport. The experimental work has included the development of improved techniques, emphasizing optical methods.The objectives were realized through a coordinated experimental and teoretical/computational research program, organized in 6 specific projects:Project 1. CFD-methods and algorithms Project 2. Spectral element simulation of ultrafiltrationProject 3. Turbulent swirling flowsProject 4. Near-wall models of turbulence & Development of experimental techniquesProject 5. Flow over bed formsProject 6. Flow past ship hull.An additional Project 0, defined for budgetary reasons, has covered common activities and indirect actions in the form of collaboration on a small scale with other research groups.General aspects are summarized in the first part of this report while the Annex at the end gives a detailed final report for each of the projects. This includes the tasks announced, the results obtained, and a list publications. Besides specific results for the selected research problems, a major product of the program has been the education and training of researchers within the field of computational and experimental fluid mechanics. This includes 12 Ph.D. candidates fully or partially funded by the program, an aboutequal number of Ph.D. candidates working on associated problems and gaining from the program, as well as a number of Masters candidates. To this should be added the many arrangements in terms of workshops, seminars and the dissemination of results which, all in all, have contributed to a strengthening of national and international collaboration.It is felt that the timing and the subject matter of the program have been very good because, as can be observed, a number of private companies and public institutions have formed or expanded CFD-groups staffed by candidates from the program.
