RISOnset of Flash Atomization in a Propellant Microjet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The parameters affecting the onset of flashing in microjets were studied. A custom atomizer assembly was designed to produce jets of propellant mixtures at different temperatures. Propellants chosen were HFA134a and HFA227ea, ...
In Vitro Evaluation of a Nasal Interface Used to Improve Delivery From a Portable Oxygen Concentrator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Portable oxygen concentrators (POCs) are widely used to administer long-term oxygen therapy (LTOT) and employ pulsed delivery modes to conserve oxygen. Efficient pulsed delivery requires that POCs are triggered by patient ...
