AGGLOMERATION OF "PYROLYTIC" AEROSOLS BY ACOUSTIC EFFECT.

Objective



ACOUSTIC AGGLOMERATION IS NORMALLY USED TO AGGLOMERATE AEROSOLS WITH MASS OF THE ORDER OF A FEW GRAMS/M TO THE POWER OF 3 AND PARTICLE LENGHT FROM 0.1 TO SEVERAL MICRONS. IN THESE AEROSOLS THE AVERAGE DISTANCE BETWEEN THE CLOSEST PARTICLES IS AROUND 10 TO 100 MICRONS. AT THIS CLOSE DISTANCE HYDRODYNAMIC INTERACTION APPEARS TO BE AN IMPORTANT FACTOR IN DETERMINING THE PARTICLE TRAJECTORIES AND THEREFORE A MAJOR MECHANISM IN THE AGGLOMERATION PROCESS. THE DEVELOPMENT OF A SYSTEM OF ACOUSTIC AGGLOMERATION CALLS FOR THE DETERMINATION OF THE OPTIMUM PRESSURE LEVEL OF THE SOUND, FREQUENCY AND PERIOD IN THE ACOUSTIC FIELD. SINCE THE ONLY MOBILE PART IN ACOUSTIC AGGLOMERATION IS THE SOUND GENERATOR THERE OUGHT NOT BE EXCESSIVE COMPLEXITY AND RELIABILITY IS PROVIDED BY A GOOD SIREN.
