Custom Wind Tunnel

The effects of co- or counter-flow gas on spray nozzle performance is critical in applications such as such as gas conditioning, wet compression, spray drying and inlet cooling in turbines.
The Wenham (blower-type) wind tunnel is specifically designed to simulate gas flow and is used to collect nozzle performance data such as drop size, spray velocity and spray coverage.  These measurements can be made using co-flow, counter-flow and cross-flow air to replicate operating conditions.

Air is drawn through a filtered inlet into a centrifugal fan and discharged into a diffuser. It then flows through a honeycomb and graduated screens to remove turbulence and create a smooth air flow. The air is then accelerated to the desired velocity through contraction and released into the test section. 

A variety of tests can be performed in the wind tunnel eliminating the need for theoretical calculations or guesswork about nozzle performance in an exact environment. Various analyzers are used in conjunction with the wind tunnel to measure drop size and velocity.  Data on additional spray characteristics such as spray angle, spray pattern, spray coverage can also be collected.
