Sweeping Effect of Sound

THE SWEEPING EFFECT OF SOUND

As we know, sound is a mechanical disorder. The sound wave resulting from this irregular movement expands and contracts at its own frequency. Thus, it creates sinusoidal oscillations (push - pull). The wavelength formed as a result of these oscillations will reach the entire area it is in. In this transference, the wave formed by the effect of molecules moving back and forth affects all molecules.

When we consider the sweeping effect of the sound in the boiler environment that sonic products are running;

During the transfer of energy as sound waves, the laminar flow hot flue gas in the boiler is also affected. Molecular mobility, velocity fluctuations and eddies form. Irregular flow motion occurs and turbulence occurs.

Thus, Ash particles that gained kinetic energy due to sound on the pipes in the boiler are caught by turbulent flow. This effect prevents the ash from making contact with the tube bundle surfaces. Also, The current ash layer in the pipe bundles is separated from the surface due to the push-pull (expansion-contraction) movement created by sound waves. It gets caught in the flue gas flow and moves away from the system.This effect is called the sweeping effect of sound.
