Princip ultrazvukov\u00e9ho \u010di\u0161t\u011bn\u00ed<\/h3>\n

Ultrazvukov\u00e9 \u010di\u0161t\u011bn\u00ed vyu\u017e\u00edv\u00e1 zvukov\u00e9 vlny s frekvenc\u00ed vy\u0161\u0161\u00ed ne\u017e 20 kHz, tedy nad hranic\u00ed sly\u0161itelnosti lidsk\u00e9ho ucha. Tyto vlny jsou generov\u00e1ny piezoelektrick\u00fdm m\u011bni\u010dem v n\u00e1dob\u011b s \u010distic\u00ed kapalinou. M\u011bni\u010d, obvykle vyroben\u00fd z keramick\u00e9ho materi\u00e1lu, se pod vlivem elektrick\u00e9ho proudu rozkmit\u00e1 a vytv\u00e1\u0159\u00ed tak ultrazvukov\u00e9 vibrace. Tyto vibrace se p\u0159en\u00e1\u0161ej\u00ed do \u010distic\u00ed kapaliny, kde zp\u016fsobuj\u00ed vznik kavitace.<\/p>\n

Kavitace: Kl\u00ed\u010dov\u00fd proces \u010di\u0161t\u011bn\u00ed<\/h3>\n

Kavitace je proces vzniku, r\u016fstu a imploze mikroskopick\u00fdch bublin v kapalin\u011b. Vlivem ultrazvukov\u00fdch vln se v kapalin\u011b vytv\u00e1\u0159\u00ed oblasti s n\u00edzk\u00fdm tlakem, kde se tvo\u0159\u00ed tyto bubliny. Jak se bubliny zv\u011bt\u0161uj\u00ed, dos\u00e1hnou bodu, kdy se prudce zhrout\u00ed (imploduj\u00ed). Tato imploze vytv\u00e1\u0159\u00ed lok\u00e1ln\u00ed tlakov\u00e9 r\u00e1zy a mikroskopick\u00e9 proudy kapaliny s vysokou energi\u00ed. Tyto r\u00e1zy \u00fa\u010dinn\u011b odstra\u0148uj\u00ed ne\u010distoty z povrchu p\u0159edm\u011bt\u016f pono\u0159en\u00fdch v kapalin\u011b.<\/p>\n
