Abstract

A nozzle for a fan assembly is described. The nozzle includes a first duct through which a first airflow moves, and a second duct through which a second airflow moves. The first duct has a first outlet for emitting the first airflow, and the second duct has a second outlet for emitting the second airflow. The first and the second outlets are arranged such that the first and second airflows collide to generate a combined airflow having a direction defined by the relative flow rates of the first and second airflows. The second duct has a constant restriction, and the first duct has a variable restriction to vary the flow rate of the first airflow.
