The characteristics of inertial drift eliminators of wet cooling towers are studied parametrically for their blade shapes, orientation with respect to gravity, solidity ratios, blade sizes, approaching air speed, and drift spectrum. The fundamental behavior of drift eliminators is revealed by nondimensional parameters. A method for the optimum design of an eliminator considering minimum cost versus performance is developed. This methodology can be integrated into the optimum design of the whole cooling system. An example is shown for this design approach. Suggestions on the design to improve the drainage of the collected water are given.
