Tsanangudzo yekuenzana

IyokuenzanaHunhu hwependi hunotsanangurwa sekukwanisa kwependi kuyerera mushure mekushandisa, nokudaro zvichibvisa kusaenzana kwepamusoro kunokonzerwa nekushandisa. Zvikuru, mushure mekushandisa pendi, pane nzira yekuyerera nekuoma, uye ipapo firimu rependi rakatsetseka, rakatsetseka, uye rakafanana rinoumbwa zvishoma nezvishoma. Kana pendi ichigona kuita hunhu hwakatsetseka uye hwakatsetseka kunonzi kuenzana.

Kufamba kwejira rakanyorova kunogona kutsanangurwa nemhando nhatu:

① muenzaniso wekona inopararira inoyerera-inobatana nechinhu chiri pasi pevhu;

② muenzaniso we sine wave wekuyerera kubva pamusoro usina kuenzana kuenda pamusoro wakatsetseka;

③ Benard vortex yakatwasuka. Inoenderana nematanho matatu makuru ekuenzana kwefirimu rakanyorova - kupararira, kuenzanisa kwekutanga uye kunonoka, apo kushushikana kwepamusoro, simba rekuchekwa, kuchinja kwe viscosity, solvent nezvimwe zvinhu zvinoita basa rakakosha padanho rega rega.

Kushanda zvisina kunaka pakuyera

(1) Maburi ekuderera
Kune zvinhu zvine simba shoma pamusoro (zvitubu zvemaburi ekudhonza) mufirimu rekuputira, zvine musiyano wekudhonza kwepamusoro nejira rakatenderedza. Musiyano uyu unokurudzira kuumbwa kwemaburi ekudhonza, zvichiita kuti mvura yakatenderedza ibude mairi yoita depression.

(2) Gwa reorenji
Mushure mekuoma, pamusoro pechifukidziro panoratidza kubuda kwakawanda kwe semicircular, kwakafanana nemafungu eganda reorenji. Chiitiko ichi chinonzi ganda reorenji.

(3) Kudonha
Firimu rakanyorova rinofambiswa negiravhiti kuti rigadzire zviratidzo zvekuyerera, izvo zvinonzi kudzika.

Zvinhu zvinokanganisa kuenzana

(1) Mhedzisiro yekumanikidzwa kwepadenga pakuenzana.
Mushure mekushandisa pendi, pachaonekwa ma interface matsva: iyo mvura/yakasimba pakati pependi ne substrate uye iyo mvura/gas interface pakati pependi nemhepo. Kana kumanikidzwa kwepakati pemvura/yakasimba pakati pependi ne substrate kwakakwira kupfuura kumanikidzwa kwepamusoro kwe substrate, pendi haizokwanisi kupararira pa substrate, uye zvikanganiso zvekuyera zvakaita sekupwanyika, kupwanyika kwevhu, uye mafisheyes zvichaitika zvega.

(2) Mhedzisiro yekunyungudika pakuenzana.
Munguva yekuomesa pendi, dzimwe zvidimbu zvisinganyunguduke dzimwe nguva zvinogadzirwa, izvo zvinozogadzira gradient yekumanikidzwa kwepamusoro uye zvinotungamira pakuumbwa kwemaburi ekupwanyika. Pamusoro pezvo, mukugadzirwa kwezvinoshandiswa mukugadzira zvinhu zvine masurfactants, kana surfactant isingawirirane nesystem, kana panguva yekuomesa, sezvo solvent ichipera, huwandu hwayo hunochinja, zvichikonzera shanduko mukunyunguduka, kugadzira madonhwe asingawirirane, uye kugadzira musiyano wekumanikidzwa kwepamusoro. Izvi zvinogona kutungamira pakuumbwa kwemaburi ekupwanyika.

(3) Mhedzisiro yekukora kwefirimu rakanyorova uye gradient yekumanikidzwa kwepamusoro pakuenzanisa.
Benard vortex – Kubuda kwemvura kwechinhu chinonyungudutsa panguva yekuomeswa kwependi kuchaita kuti pave nekusiyana kwekupisa, kuwanda uye kusimba kwenzvimbo pakati pepamusoro nemukati mependi. Kusiyana uku kuchatungamira mukufamba kwakashata mukati mependi, zvichigadzira chinonzi Benard vortex. Matambudziko ependi anokonzerwa nemavortices eBenard haasi maganda eorenji chete. Mumasystem ane pigment anopfuura rimwe chete, kana paine musiyano mukufamba kwezvikamu zvepigment, mavortices eBenard anogona kukonzera kuyerera nekutumbuka, uye kushandiswa kwepamusoro kuchakonzerawo mitsetse yesiriki.

(4) Mhedzisiro yetekinoroji yekuvaka nenzvimbo yakapoteredza pakuenzana.
Munguva yekuvaka nekugadzira firimu, kana paine tsvina yekunze, inogonawo kukonzera kusawirirana kwakadai semaburi ekupwanyika uye maziso ehove. Zvinosvibisa izvi zvinowanzobva mumafuta, guruva, mhute yependi, utsi hwemvura, nezvimwewo zvinobva mumhepo, zvishandiso zvekuvaka uye substrates. Hunhu hwependi pachayo (senge viscosity yekuvaka, nguva yekuomesa, nezvimwewo) huchavawo nemhedzisiro yakakura pakuenzana kwependi. Viscosity yekuvaka yakanyanya uye nguva pfupi yekuomesa inowanzoita kuti pave nechitarisiko chisina kuenzana.
