Fundamental Study of Dust Remover Applying the Flow Mechanism of Fluidics

As a part of the investigation on the device to remove the dust on the panel of solar heat collector or solar cell, the new type of sprinkler applying the flow mechanism of the fluidic devices have been designed and improved. In this study, the effects of the exit width of sprinkler on the spread angle and the distribution of sprinkled water have been investigated. As a result, the spread angle of sprinkled water widens as the exit width becomes large. However, at a certain exit width. the spread angle has a maximum value, then it lessens gradually. The distributions of sprinkled water change greatly with the exit width of sprinkler.
