As a part of the investigation of a device which removes dust particles from the panel of a solar heat collector or solar cell, a sprinkler which applies a flow oscillating mechanism has been designed and improved. In this study, the effects of the geometrical condition on the spread angle and the distribution of the sprinkled water are investigated. From the results, it is found that the spread angle of the sprinkled water widens as the exit width of the sprinkler and diameter of the pressure recovery hole become larger. However, at a certain exit width or diameter, the spread angle obtains a maximum value, then decreases gradually. The distribution of sprinkled water changes also with the exit width and the diameter. Moreover, the output power of the solar cell has been measured in order to prove the effects of this sprinkler.
