In a liquid containing many bubbles, a huge instantaneous pressure is generated when the liquid of the bubbles collapses and rebounds. When the collapsed bubble is close to the solid boundary of the overflow, the repeated action of high pressure generated by the continuously collapsing bubble in the water flow can destroy the solid surface, resulting in cavitation. The bubbles burst near the surface of the vegetable, and the hampir spherical bubbles move with the jet to the vicinity of the rigid solid surface. Sejak the banjir jet bentuk a thin diffuse current on the solid surface, the lateral flow of the liquid flow between the bubble and the vegetable surface makes the liquid pressure of the end of the bubble wall near the vegetable surface (called the near wall) and the farther end (called the far wall) of the bubble wall is low, and the centripetal movement speed is slower than that of other parts. In the center of the bubble to the vegetable surface movement, the distance between the near wall and the vegetable surface is basically changed, in order to maintain the conservation of momentum (not considering the influence of liquid viscosity), the bubble must do accelerated movement, the far wall is recessed inward, close to the near wall, the near wall is penetrated to form a high velocity microjet, this microjet titik ke the sayuran permukaan% 2c its kerusakan dan erosi kemampuan adalah sangat kuat. Melalui perhitungan dan aktual pengukuran% 2c kapan melayang gelembung runtuh, the microjet kecepatan dekat the solid dinding bisa mencapai 70% 7e180MPa. Such a tinggi dinamis tekanan bisa sepenuhnya bersih jauh polutan on the permukaan dari sayuran dan mempersingkat the membersihkan waktu. Kapan gelembung are terus-menerus dihasilkan dalam air. Meningkat. Kapan itu suap, the dampak tekanan dari gelembung runtuh terus menerus tindakan pada permukaan dari pada sayuran untuk efektif menghapus polutan pada permukaan dari sayuran. Terima kasih Anda untuk menyukai dan membaca, kemudian kami akan melihat Anda dalam the berikutnya masalah.
