What is the importance of spray patternation

1. What is the importance of spray patternation? Spray patternation is also known as spray pattern, it is a way of evaluating the particular characteristics and performance of the spray particles on the surface. Patternation can be also defined as a method of analyzing the spray pattern on the basis of its physical aspects. It is commonly used in various industrial activities for nozzle testing. Based on the application, the spray patternation method can be used to test a wide variety of nozzles and injectors. We use numerous items in our daily lives that are based on spray techniques, such as body sprays, hair sprays, makeup sprays, inhalers, and more. Highly specialized spray patternation is very crucial for industrial purposes, as any detail missing in the symmetry of the spray pattern can hinder the desired results. For example; the wrong spray pattern in spray coating can lead to the uneven coating of the surface, too thin coating is likely to chip off, and too thick coating leads to a shabby look. Similarly, sprays in internal fuel combustion should be symmetric to avoid the excess supply of fuel that might lead to an unwanted amount of heat and combustion. Now you can wonder about the results of wrong spray patterns in a breathing patient’s inhaler and a farmer’s pesticide sprayer. Different Methods of spray patternation There are two major types of diagnostic tools knows as mechanical patternators and optical patternators to test the spray patterns. These diagnostic tools estimate the expansion of spray emission from the sprayer and identify the physical structure of the spray particles as well. The tools identify the spray pattern by two methods, as follows: Mechanical patternation- This is the simplest method to identify the spray pattern. The mechanical patternator analyze the spray after collecting the sprayed material from the surface. This basically informs about the amount of spray distribution throughout the surface. Mechanical patternation is likely to have errors and inaccurate reading. Optical patternation- This diagnostics technique is much reliable than mechanical patternation. It is not as direct as the other method; it uses optical instruments to closely analyze the spray pattern. This technique includes a light sheet in the process to understand everything about the distribution of the spray through the surface rather than just knowing the mass of the spray. Optical patternation is likely to provide an accurate reading. What information can be obtained by a spray patternation test?  Area of the spray pattern

2. Structure of the sprayed droplets  Angles of the sprayed cone  The density of the angular spray  Drop density through the surface  Number of the patternator  Asymmetry ratio in the spray  To obtain the information about the drop size, you might require to use some other means. The right spray pattern is very crucial for the industries to maintain the proper functionality of the devices and assist the required results. Source: https://www.enurga.com/spraypattern.htm
