 The Importance of Drop Size in Gas Conditioning
Measuring drop size and velocity is important in many applications but is critical in gas cooling. The catalyst for change is carried within the drop and will affect system performance. In addition to Sauter Mean Diameter data, Dmax data should be evaluated because of its impact on wetting. It is important that you obtain accurate information and understand how that data was collected. There are different ways to collect and record drop size data but the industry-preferred guideline is ASTM Standard E799. While ASTM E799 permits Dmax to make up as much as 1% of the volume, all of our measurements keep Dmax at 0.20% of the volume. This conservative measurement method means we can precisely predict spray system performance. As you are evaluating nozzle options, be sure to ask about the drop size measurement techniques. Many manufacturers provide only imprecise theoretical information.
All of our data and 70 years of drop size expertise is available to you at no charge during the process of selecting and configuring your gas conditioning system. Should your application require special additional testing, our Spray Analysis and Research Services group will design and quote the testing required. Utilizing the industry’s most fully equipped, state-of-the-art testing lab, Spray Analysis and Research Services has the expertise and equipment to help gather and analyze drop size performance data to help determine your exact requirements and ensure your gas conditioning system delivers optimal performance.
