Effect of Upstream Wake on Shower-Head Film Cooling by Ping-Hei Chen, Jr-Ming Miao

“…The present study aims to investigate the effect of an upstream wake on the convective transport phenomena over a turbine blade with shower-head film cooling. A naphthalene sublimation technique was implemented to obtain the detailed mass transfer distributions on both suction and pressure surfaces of the test blade. …”

Substrate Effect on Plasma Clean Efficiency in Plasma Enhanced Chemical Vapor Deposition System by Shiu-Ko JangJian, Ying-Lang Wang

“…The high resolution inductively coupled plasma mass spectrometer (HR-ICP-MS) is used to analyze microelement of metal ions on the surface of shower head in the PECVD chamber. According to Cu substrate, the results show that micro Cu ion and the CuOx bonding can be detected on the surface of shower head. …”
