Abstract:

The need to measure the size of drops in a fluid spray has resulted in the invention of many techniques to catch a drop sample. Since the standard methods of spray sample collection were not satisfactory for the problem at hand. A method for catching spray droplets was devised whereby they were not absorbed or destroyed. The theoretical spread factor analysis was experimentally verified for drops less than about 450 micrometers. For larger drops, the spread factor was larger than that theoretically predicted which implies a smaller contact angle for larger drops. The test method and results are discussed.
