Izinto eziphambili eziza kuchaphazela amandla ezixhobo ze-ultrasonic zokutyumza zihlulwe nje zibe yi-ultrasonic frequency, i-surface tension kunye ne-viscosity coefficient ye-liquid, ukushisa kwamanzi kunye ne-cavitation threshold, ekufuneka ihlawulwe ingqalelo.Ngeenkcukacha, nceda ubhekisele koku kulandelayo:

1. Ultrasonic frequency

Ukunciphisa i-frequency ye-ultrasonic, kulula ukuvelisa i-cavitation kwi-liquid.Ngamanye amazwi, ukwenza i-cavitation, ukuphakama kwe-frequency, isandi esikhulu esifunekayo.Ngokomzekelo, ukuvelisa i-cavitation emanzini, amandla afunekayo kwi-ultrasonic frequency kwi-400kHz ngamaxesha angama-10 amakhulu kunoko kwi-10kHz, oko kukuthi, i-cavitation iyancipha ngokunyuka kwe-frequency.Ngokubanzi, uluhlu lwamaza ngama-20 ~ 40KHz.

2. Uxinzelelo lomphezulu kunye ne-viscosity coefficient yolwelo

Ubuninzi bobunzima bomphezulu wolwelo, ukuphakama kwe-cavitation intensity, kunye ne-cavitation encinci.I-liquid ene-coefficient enkulu ye-viscosity inzima ukuvelisa iibhubhu ze-cavitation, kwaye ilahleko kwinkqubo yokusabalalisa nayo inkulu, ngoko ke akulula ukuvelisa i-cavitation.

3. Ubushushu bolwelo

Ukuphakama kweqondo lokushisa lolwelo, kokukhona kuthandeka ngakumbi kwisizukulwana se-cavitation.Nangona kunjalo, xa iqondo lokushisa liphezulu kakhulu, uxinzelelo lomphunga kwi-bubble luyanda.Ke ngoko, xa i-bubble ivaliwe, i-buffer effect iyaphuculwa kwaye i-cavitation iyancipha.

4. Umda weCavitation

I-Cavitation threshold yisandi esiphantsi somsindo okanye i-amplitude yoxinzelelo lwesandi obangela i-cavitation kwi-medium medium.Uxinzelelo olubi lunokwenzeka kuphela xa i-alternating isandi soxinzelelo lwe-amplitude inkulu kunoxinzelelo lwe-static.Kuphela xa uxinzelelo olubi ludlula i-viscosity ye-liquid medium iya kwenzeka i-cavitation.

I-cavitation threshold iyahluka kunye nemidiya eyahlukeneyo yamanzi.Kwi-medium liquid medium, i-cavitation threshold iyahluka ngobushushu obuhlukeneyo, uxinzelelo, i-radius ye-cavitation core kunye nomxholo wegesi.Ngokuqhelekileyo, i-gas content medium medium, iphezulu i-cavitation threshold.Umda we-cavitation unxulumene ne-viscosity ye-liquid medium.I-viscosity enkulu ye-liquid medium, iphezulu i-cavitation threshold.

I-cavitation threshold ihambelana ngokusondeleyo kunye nokuphindaphinda kwe-ultrasound.I-high frequency ye-ultrasound, iphezulu i-cavitation threshold.Iphezulu i-frequency ye-ultrasonic, kunzima ngakumbi kwi-cavitation.Ukuze sivelise i-cavitation, kufuneka sandise amandla ezixhobo zokutyumza ze-ultrasonic.
