Custom built wind tunnel tests nozzle performance in critical applications

WHEATON, IL, March 10, 2003 — Spraying Systems Co. has added a Wenham (blower-type) custom wind tunnel to its Spray Analysis and Research Services laboratory, expanding its already extensive research capabilities.

The wind tunnel is specifically designed for testing spray nozzle performance in environments with co-air and cross-air flows. The 35-ft. tunnel provides uninterrupted, steady air flow in a test area large enough to accommodate spray manifolds

“We took our 60 years of experience in spray analysis and partnered with Engineering Laboratory Design, who are the experts in aerodynamic laboratory equipment design, to build a wind tunnel that is state-of-the-art and designed specifically for spray testing,” said Rudolf J. Schick, Research Director for Spraying Systems Co.

“This one-of-a-kind wind tunnel offers customers the unique capability of maximizing nozzle and manifold performance for our customers with gas conditioning, wet compression, spray drying of products and inlet cooling applications.”

A variety of tests can be performed in the new wind tunnel eliminating the need for theoretical calculations or guesswork about nozzle performance in an exact environment.

Using velocities ranging from 400 to 4,500 feet/min., the wind tunnel can test the following spray characteristics: spray angle, spray pattern, spray coverage, drop size, evaporation rate, dwell time and residence time.
