Abstract:

Efficiency of aspiration 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 air velocity field into the inlet with an analytical solution to the particle equations of motion to describe particle trajectories. 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 for a wide range of airstream, sampling inlet, and particle conditions.
