Abstract

Self-excited vibration of a film caused by air flow is analyzed to realize an electric power generator driven by fluid energy which exists in various artifacts. First, generation of the self-excited vibration is verified through experiments. Second, an approximate calculation method on the basis of the experimental results is contrived. Third, with the appropriate analysis, effect of the inlet air pressure, film tension, boundary pressure on the vibration frequency and easiness of vibration generation are clarified. Also the calculated results are compared with experimental ones to verify the validity of the analysis.
