EFFECT OF HEATING AND IONIZATION OF FOUR ATOMIZING GASES ON THE SPRAY CHARACTERISTICS OF A HIGH VOLUME LOW PRESSURE SPRAY ATOMIZER

摘要: OF THESIS EFFECT HEATING AND IONIZATION FOUR ATOMIZING GASES ON THE SPRAY CHARACTERISTICS A HIGH VOLUME LOW PRESSURE ATOMIZER The disintegration of a liquid jet emerging from nozzle by high speed gas stream has been under investigation several decades. result the is droplet formation. This process referred to as atomization. Industrial applications use atomization method for applying coatings substrates. It reported that other atomizing gases instead compressed plant air will positively affect paint size distributions, spray patterns and finish qualities; furthermore, ionization heating was qualities. Although techniques have studied in past, lack specific information remains about how actually affects formation size, quality. To determine effect different gases, heating, methods were used. distribution captured with laser diffraction, while large-scale characteristics flow recorded Infrared thermography. In process, novel developed measuring secondary breakup spray.
