   Abstract:
   A theoretical model was developed based on a fluid mechanical force balance to describe the behavior of particles in pulsing airflow. Several attributes distinguished this flow regime from those that have been widely studied: (1) The fluid was a gas; (2) the particles were much larger than aerosol; (3) the airflow was pulsed, as opposed to the more commonly studied oscillatory flow; and (4) the flow was vertical, requiring the inclusion of a body force in the expression. Much effort in the theoretical formulation and calibration was devoted to the acceleration effect, due to its importance in time-varying flow. Computer models were developed and presented that were used in laboratory calibration of the theoretical expression and in modeling particle separation in rising, pulsing airflow.
