Abstract : The subject of the report is the force exerted on a spherical inclusion in a liquid by an acoustic stationary wave. Experimental and theoretical values are presented for the minimum acoustic pressure amplitudes required to trap small, individual droplets of various liquids near a pressure antinode in a stationary sound field in a cylinder filled with water. The liquids used were paraldehyde, hexane, benzene, toluene, chlorobenzene, and carbon tetrachloride. Droplet radii ranged from 400 to 800 micrometers and acoustic pressure amplitudes ranged from 1 to 15 bars. Calculated and observed values are in agreement if the compressibility of the liquid droplets is considered. (Author)
