dc.description.abstract | The particle deposition onto the duct wall has received attention owing to the possibility of enhancing the indoor air quality. The particle flux onto the wall is a product of the deposition velocity and the local particle concentration, and there are only a few attempts to modulate the local particle concentration. In this study, we use a synthetic jet to change the particle concentration distribution due to the convenience of the synthetic jet. The synthetic jet actuator is attached to the vertical wind tunnel, and the resulting air flow and the particle concentration is reported. The synthetic jet is characterized by the Reynolds number based on the impulse and dimensional frequency. The Reynolds number seems to affect the inclination of the particle concentration far from the orifice, which can be explained by the impulse on the particles. The dimensionless frequency is related with the number of synthetic jet pulses affecting the particles, and affects the maximum concentration. The product of the two parameters is linearly related to the absolute change of the particle concentration. | - |
