Abstract

The removal of fine particles adhering to a wall has been studied using a high-speed two-dimensional air jet paying particular attention to the geometric constitutions of the removal equipment and the duration of air jet blowing. The experimental results showed that the stable high efficiency region was confined to the vicinity of the impinging point of the air jet and depended on the impinging angle. The high efficiency region was well estimated by a new model where the impinging region was introduced based on the two dimensional free jet theory. The effect of the nozzle-wall distance and the particle diameter were also estimated. The change in the removal efficiency with time was also well represented by a model assuming that the efficiency was proportional to the number of removable adhered particles. In addition, the removal characteristics of the sequential pulse jet were the same as those obtained by a one-pulse jet as long as the total duration of the air jet was kept constant. The change in the efficiency with pulse number was also represented by the same model.
