Gasdynamic Simulation of Aerosol Deposition Method
The gas flow of aerosol deposition method (ADM) is simulated using the method of computational fluid dynamics (CFD), and the velocity of particles flowing in the gas flow is also calculated by numerically integrating Newton’s second law of motion. The process gas is nitrogen and the particle material is Pb(Zr,Ti)O3 (PZT). The calculated particle velocities are compared with experimental results...
متن کاملThe statistical convergence of aerosol deposition measurements
The spatial distribution of deposited aerosol particles shows substantial statistical variation. This variation is especially important for sampling techniques having a high spatial resolution, such as laser-based methods, or for experiments involving a small sample size (few identical locations measured) or a short duration. This paper develops a criterion to ensure adequate statistical conver...
متن کاملAerosol properties and lung deposition.
important experiments on total and regional lung deposition for healthy subjects has recently been published by the International Commission on Radiation Protection (ICRP) [2]. The mean values of experimental deposition data are approximated by mathematical expressions, which are then implemented into a computer program [3] that is commercially available on diskette. Since this model is applica...
متن کاملBronchiolar aerosol deposition and clearance.
We have often, and over a long time, thought of the "small airways" as a mystery zone or a quiet zone [1]. Relative to central bronchial generations, the total crosssectional area of each bronchiolar generation is large. Airflow resistance should in consequence be low. Considerable changes due to disease could, thus, occur with little chance of being detected by conventional lung function testi...
متن کاملUltrafine Aerosol Deposition in Planar Channel
A technique was developed for measuring the deposition of aerosols from 0.01 to 1pm diameter in a turbulent, planar channel flow. The ultimate goal of this project was to investigate ultrafine aerosol deposition in lung passageways. A procedure was developed to measure ultrafine aerosol deposition in a turbulent planar channel. Titanium tetrachloride, TiCl4, reacting with atmospheric water vapo...
