摘要：

We have developed a unified aspiration efficiency model for sampling with round inlets at 0-90° forward angles from horizontal aerosol flows. The aspiration efficiency is represented by a single equation as a function of the sampling angle, the ratio of wind to inlet velocity, and different inertial parameters for 0-60° and 45-90° sampling. The equation for 45-90° sampling is an extension of the Laktionov equation for 90°. The new model fits the experimental data within experimental accuracy. © 1990, American Chemical Society.
