Acoustic Flows In Closed Space • The flows in liquid and gas mediums, during intensity acoustic wave propagation, are caused by liquid (gas) viscosity. • Into infinite mediums the acoustic flows are laminar and directed lengthways wave propagation vector. • In the stationary waves conditions acoustic flows are closed. Near the interface layer acoustic flows rises a turbulence. • The velocity of acoustic flows secondary-degree depends from sound pressure and in range 140- 150 dB is 6-10 m/s Scheme of acoustic flows in closed space The acoustic flows is main driving force of acoustic drying in 1401 40-150 dB sound pressure level range. Acoustic flows speeding up evaporation and provides humidity removal from drying zone 6
Microflows Near Obstacle • When the acoustic wave interacts with drying cloth, in immediate proximity to humidity fibers the microflows are arises. • Low intensity waves provides laminar microflows that do not influence to drying speed. • When intensity of acoustic waves reach a critical value, the microflows turn into turbulence and displace a bound laminar flow, that assists for mass transfer process. Laminar mode Re1200 Microflows near the obstacle along with acoustic flows appreciably intensify mass changes processes at 140-150 150 dB range 7
