A theoretical model is developed that is based on a fluid mechanical force balance to describe the behavior of particles in pulsing airflow. Several attributes distinguish this flow regime from those that have been widely studied: the fluid is a gas, the particles are much larger than aerosol and the airflow is pulsed, as opposed to the more commonly studied oscillatory flow and the flow is vertical, requiring the inclusion of a body force in the expression. Computer models are developed and presented that are used in laboratory calibration of the theoretical expression, and in modelling particle separation in rising, pulsing airflow. Theory shows separations based upon density that are not possible in steady rising airstreams. Experimentation with air classifier designs suggested by the model shows greatly increased separation efficiency.
