Description

ность роста зародышей кавитации в результате, так называемой, выпр мленной диффузии газа в пузырек и увеличени , таким образом, концентрации кавитационных пузырьков.the growth of cavitation nuclei as a result of the so-called rectified diffusion of gas into the bubble and thus increasing the concentration of cavitation bubbles.

Помимо диссипации энергии схлопывающихс  пузырьков при наложении ультразвукового пол  все кавитационные пузырьки испытают насыщение воздухом за счет разрушени  мономолекул рного сло  адсорбированных на поверхности пузырьков молекул жирных кислот, -за счет увеличени  поверхности стенок пузырьков при потере ими сферичности и выпр мленной диффузии. Воздухонасыщение значительно сокраща т величину давлени  во фронте ударной волны, идущей от захлопнувшегос  пузырька, в результате менее совершенного схлопывани  за счет демпфировани .In addition to dissipating the energy of collapsing bubbles when applying an ultrasonic floor, all cavitation bubbles will experience air saturation due to the destruction of the monomolecular layer of fatty acid molecules adsorbed on the surface of the bubbles, due to the increase in the surface of the bubbles when they lose sphericity and rectified diffusion. Air saturation significantly reduces the pressure in the shock wave front coming from the slammed bubble, resulting in a less perfect collapse due to damping.

Использование предлагаемого изобретени  позволит улучшить эксплуатационные показатели устройств при работе их в кавитациониых режимах, снизить разрушительную способность кавитации и, повысить межремонтный ресурс работы.The use of the proposed invention will improve the performance of devices when operating in cavitation modes, reduce the destructive ability of cavitation and increase the service life between repairs.
