Novel Cardiac Assist Valve With a Purge Flow in the Valve Sinus
ASAIO Journal, 1998Clinical applications of cardiac assist systems continue to have a severe problem, that of thromboembolic complications. The problem originates mainly at the valves, which are usually made of a antithrombogenic material, such as bovine pericardium. However, the valve housing is made of a less suitable material, and wherever the blood flow is stagnant ...

Office Uroflowmetry Using a Maximum Flow Rate Purge Meter
Journal of Urology, 1979The use of a purge size rotameter for the determination of maximum urinary flow rates represents an inexpensive and non-invasive method to detect obstructive or neurogenic lower urinary tract abnormalities. We have used the device to identify successfully selected patients with such abnormalities.

Calculation of age and local purging flow rate in rooms
Building and Environment, 1987Abstract The local purging flow rate and the local age in ventilated rooms are numerically investigated; both quantities are calculated in an isothermally ventilated two-dimensional room, the latter in two buoyantly ventilated three-dimensional rooms as well.

Numerical analysis of optical mirror jet-flow purging characteristics
AOPC 2021: Advanced Laser Technology and Applications, 2021Efficient cleaning of pollutants on the optical lens surface is a very important and urgent research topic in the field of laser processing. Therefore, based on the free jet theory of fluid dynamics, the flow field characteristics of the optical system lens are theoretically analyzed and numerically simulated, and the flow field distribution of the ...

Recirculation of Purged Flow in an Adiabatic Counterflow Rotary Dehumidifier
Journal of Heat Transfer, 1984The average process stream outlet humidity ratio of an adiabatic counterflow dehumidifier can be lowered if a portion of the process outlet stream is purged from the bulk flow. The purged stream can be recirculated and introduced at the inlet of the regenerating period. In this paper, the performance of such a purged counterflow dehumidifier is studied.

Gas particle flows about a Cobra probe with purging
Computers & Fluids, 1995Abstract The detailed flow behaviour around a special purpose four-hole Cobra Pilot pressure probe with purging is investigated computationally in gas and gas-particle flows. The incompressible steady state Navier-Stokes equations for the gas phase are solved numerically using a general purpose computational fluid dynamics code. Computational results

Analysis of helium purge flow in a solid breeder blanket
Fusion Engineering and Design, 1989A numerical analysis of the purge flow in sphere-pac solid breeder has been carried out using the modified Darcy equations. The results show that: (1) the tritium accumulation in the purge and permeation through the wall is not a concern, (2) pressure drop expressions for fully developed flow are applicable in evaluating the pressure drop in a ...

Flow Electroporation with Pulsed Electric Fields for Purging Tumor Cells
2008Electroporation has been used in biological laboratories for many years to transiently porate cell membranes and permit plasmid or protein transfection. It has been shown that the application of pulsed electric fields (PEFs) of defined strength will kill off larger cells and select for viable small cells, in samples containing heterogeneous cells. This

Low-Flow Purging and Sampling Guidance
2003The procedures in this guidance document are specific to Low-Flow Purging and Sampling (LFPS) of monitor wells in New Jersey. The purpose of Low-Flow Purging and Sampling (LFPS) is to collect groundwater samples from monitor wells that are representative of ambient groundwater conditions in the aquifer.

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.
