This work presents an experimental study of particle removal from surfaces by means of a pulsed air jet directed toward the particle-laden surface. During the experiments, solid particles were dispersed over the surface, forming a layer of particles that did not touch each other. Under these conditions, resuspension of an individual particle was independent of the number of particles and their location.We attempt to explain the observed phenomena by analogy to heat transfer enhancement by pulsed jets. It is expected that since pulsed jets are effective in surface cooling, their application to improved surface cleaning should be promising.For a pulsed jet, we investigated the effect of pulse frequency on particle removal. It was found that particle removal ef ciency could be signi cantly affected by the frequency of the jet. In particular, for a xed jet velocity, the ef ciency increases with frequency, reaches a maximum, and then decreases.
