DTIC ADA139566: Nozzle Tests for Simulating Heavy

More Book Details

Description of the Book:

Tests were conducted with a vibrating tube nozzle system to assess the ability of the system to realistically simulate the natural heavy rain environment at wind tunnel airspeeds of 65 to 125 mph. The nozzle system was specifically designed to achieve the large droplet sizes (-2mm) that are characteristic of the heavy rain environment. The nozzle system also produced the appropriate total water volume to simulate rain rates from 25 mm/hr to over 500 mm/hr. The test results established the allowable velocity differential between the airstream and water velocity that resulted in large droplet formation. Velocity differentials exceeding the allowable or critical value resulted in the shattering of large drops into a spectrum of much smaller drops
