- Abstract
- Aspiration efficiency of particles from a flowing airstream into a thin walled sampling inlet is accurately predicted using a numerical model. The model combines the Boundary Integral Equation Method for predicting the velocity field into the inlet with an analytical solution to the particle equations of motion. A two and a three dimensional model are examined. Results for the three dimensional model correlate well with an empirical model of aspiration efficiency. The method can be generalized to a wide range of airstream, sampling inlet, and particle conditions.
