Real simulation of ultrasound waves disrupting the heat restricting laminar boundary air layer
This video is a real simulation and it shows how effective the ultrasound waves disrupts the heat-restricting stagnant air right above any object.
The green and yellow areas shows the velocity of the fast moving airflows just above the surface of the object. The closer air is to the surface, the slower is the velocity due to the friction with the surface. The dark blue area is stagnant air also knows as the laminar sublayer. The laminar sublayer is heat restricting and takes out energy from the steam treatment but when combined to the ultrasound, the ultrasound waves can disrupt the laminar sublayer and thereby improve heat transfer to the surface.
The time rate in this video is significantly reduced in order to show the pulsing ultrasound waves. The sound waves push the boundary layer aside and allow heat to reach the surface rapidly.
