An Intraventricular Axial Flow Blood Pump Integrated With a Bearing Purge System
ASAIO Journal, 1995The future development of implantable axial flow blood pumps must address two major issues: mechanically induced hemolysis and shaft seal reliability. The recent revisions to our miniature intraventricular axial flow left ventricular assist device (LVAD) were aimed particularly at addressing these concerns.

Effects of Purge Flow Configuration on Sealing Effectiveness in a Rotor-Stator Cavity
Volume 5B: Heat Transfer, 2017Secondary air is bled from the compressor in a gas turbine engine to cool turbine components and seal the cavities between stages. Unsealed cavities can lead to hot gas ingestion, which can degrade critical components or, in extreme cases, can be catastrophic to engines. For this study, a 1.5 stage turbine with an engine-realistic rim seal was operated

FOUP purge performance improvement using EFEM flow converter
2016 27th Annual SEMI Advanced Semiconductor Manufacturing Conference (ASMC), 2016Front Opening Unified Pod (FOUP) purging with nitrogen or clean dry air (CDA) is well known as the most effective method to protect wafers inside FOUPs from internal as well as external contaminations, e.g. particles, airborne molecular contaminants, humidity and oxygen, which can potentially damage integrated circuits (IC) and significantly impact ...

Examination of material outgassing in the air and purging flow environments
SPIE Proceedings, 2004This paper examines outgassing kinetics in the air and purging flow environments, as well as including a comparison to full outgassing in vacuum. The experimental data and models reported in the literature on the material outgassing in those environments are examined and summarized.

The effect of purge gas flow rate on thermogravimetric experiments
Thermochimica Acta, 1983This paper describes research carried out to elucidate the reasons for the unusual behaviour of lead azide, Pb(N,),, in thermogravimetric TG and differential scanning calorimetry DSC experiments reported by other workers [ 11. They noted that in a DSC experiment Pb(N,), behaved in the expected manner (i.e.
