Patent number: 7487686Abstract: A high-precision vortex flow meter includes a blunt body having a predetermined dimension and being arranged inside a fluid channel to serve as a vortex shedder. The vortex flow meter also includes a temperature detecting device for detecting the vortex shedder temperature and a temperature control element for adjusting the vortex shedder temperature. A frequency measuring device is arranged in the downstream section of the blunt body for detecting the vortex shedding frequency. From the measured temperatures of the upstream fluid flow and that of the blunt body, an effective temperature and a temperature ratio are calculated. The kinematic viscosity of the fluid is looked up from database. By using the relationship between the Strouhal number and Reynolds number, the fluid flow rate is calculated. By employing different blunt body temperature, the measurement range of the flow meter can be broadly extended.Type: GrantFiled: April 27, 2007Date of Patent: February 10, 2009Assignee: National Taiwan UniversityInventors: An-Bang Wang, Ming-Hsun Wu, Yi-Hua Wang, I-Chun Lin, Chia-Chih Chen, Shiming Lin

Publication number: 20080145537Abstract: A micro patch coating device includes a coating die with a micro channel structure. A coating fluid is supplied through a coating fluid inlet and an auxiliary fluid is supplied through an auxiliary fluid inlet. After a segment of a predetermined length of the coating fluid is formed at a two-phase fluid output section, the coating fluid flow is intercepted. In turn, a segment of predetermined length of the auxiliary fluid is formed at the two-phase fluid output section, and then the auxiliary fluid flow is intercepted. A two-phase fluid is formed and flows out of the coating die to the substrate to form micro patches thereon.Type: ApplicationFiled: May 30, 2007Publication date: June 19, 2008Inventors: An-Bang Wang, I-Chun Lin, Yi-Hua Wang, Chih-Kung Lee
