Reducing Thickness Of Water-Air Interface Layer Air flow Air flow Evaporation Diffusion Interface Layer Water Convective drying Water Acoustic drying • Near the wet material surface are presence the interface layer, that is impediment for mass changes process • Reducing the interface layer thickness provides increasing the evaporation speed. • The thickness of interface layer depends from diffusion and hydrodynamic processes. • During the convective drying air flows in interface layer are laminar and thickness of interface layer defines by diffusion processes • In the high-intensity acoustic fields thickness of interface layer seriously decreases that caused by turbulent flows and microflows 8
Radiation Pressure Radiation pressure Ultrasound Removed water Water in material • Radiation pressure is steady component of total pressure that influence to solid in acoustic wave. • The cause of radiation pressure is a transfer a part of wave mechanical impulse to a solid during absorption or reflection the acoustic wave. • The radiation pressure, that arises in intensity acoustic field (more than 135 dB) capable to squeeze out water drops from material 9
