Real simulation of ultrasound waves disrupting the heat restricting laminar boundary air layer
This video is a real simulation of ultrasound waves, which are cutting through the different layers of air and disrupting the heat-restricting stagnant air right above any object.
The green and yellow moving areas are the turbulence air. The closest we get to an object, the darker becomes the colors and the lower are the air velocities. The very dark blue area represents the boundary laminar air layer.
The time rate must be significantly reduced in order to be able to show the super fast ultrasound waves. In this time frame, turbulence and the boundary layer does not change and thus looks as it is frozen. The sound waves push the boundary layer aside and allow heat to reach the surface rapidly.
