| Abstract |
In the article, a numerical model for determining the aspiration component of overall sampling efficiency for an arbitrarily shaped thin-walled inlet is presented. The numerical simulations presented here are limited to examining the effect of pitch angle and velocity ratio on the aspiration efficiency. Both two- and three-dimensional numerical predictions of aspiration efficiency are compared with empirically based predictions from the unified model of Hangal and Willeke (1990). In general, the more realistic three-dimensional simulations were in better agreement with the unified model. (Copyright (c) 1993 Elsevier Science Publishing Co., Inc.) |
