<strong>Acoustic</strong> Flows <strong>In</strong> Closed Space<br />
• <strong>The</strong> flows in liquid and gas<br />
mediums, during intensity<br />
acoustic wave propagation, are<br />
caused by liquid (gas) viscosity.<br />
• <strong>In</strong>to infinite mediums the acoustic<br />
flows are laminar and directed<br />
lengthways wave propagation<br />
vector.<br />
• <strong>In</strong> the stationary waves conditions<br />
acoustic flows are closed. Near<br />
the interface layer acoustic flows<br />
rises a turbulence.<br />
• <strong>The</strong> velocity of acoustic flows<br />
secondary-degree depends from<br />
sound pressure and in range 140-<br />
150 dB is 6-10 m/s<br />
Scheme of acoustic flows in closed space<br />
<strong>The</strong> acoustic flows is main driving force of acoustic drying in 1401<br />
40-150 dB sound<br />
pressure level range. <strong>Acoustic</strong> flows speeding up evaporation and provides humidity<br />
removal from drying zone<br />
