Test methods have been developed for evaluating the performance of chevrons with respect to capacity, pressure drop, removal efficiency, and plugging tendency. The first three of these parameters are presented for 18 different commercial vertical-flow chevrons. For the chevrons tested and the range of test conditions studied, the capacities ranged over a factor of 2, the pressure drops ranged over a factor of 10, and the droplet penetration ratio ranged over a factor of 20 or more. All of the chevrons tested gave essentially complete removal of droplets larger than 70 Am in diameter, and some gave essentially complete removal of 10 Am droplets. These data can be used, along with other selection criteria, to compare various chevron designs for retrofit or new installations.
