Current research shows that pulse combustion impingement drying is an improvement over the steady impingement drying currently in commercial use. Pulse combustion impingement has higher heat transfer rates and a lower impact on the environment. Commercialization of pulse impingement drying is the goal of the Pulsed Air Drying group at IPST. To that end the objective of this project is to develop a system that will allow researchers to measure heat transfer rates at the impingement surface from the impinging air. A water cooled impingement plate with temperature and heat flux measuring capabilities was developed which accurately measures and records the desired information. The impingement plate was tested and its results were verified by comparison with previous literature. Finally a preliminary comparison between steady and pulse combustion impingement was carried out. The study shows pulsed combustion impingement to be superior to steady impingement.
