The film formation during the spray/wall impingement has attracted more attention. present study investigated characteristics of pressure-swirl nozzle by applying contact-free optical method. According to experimental results, distance had a slightly significant effect on actual spray angle than mass flow rate, and maximum changing value was 34.6°. bulge at center surface became insignificant w...

Abstract Aiming at the design and analysis of flexible film building rigid large complex structure system, this paper carried out simulation dynamic characteristics thin with concentrated mass. The structural connectors high stiffness relatively mass are simplified as is a biaxially tensioned cross material sample. influences pretension, quality, size on natural frequency samples analyzed. resu...
