Tuubbada go'doonsan waa nooc ka mid ah dhuumaha leh jeexdin ka dib. Caadi ahaan: tuubooyin wareeg ah, tuubo jeexan oo oval ah, iwm. waxaa lagu magacaabaa tuubo googo'an sababtoo ah jeexdin muuqda ayaa laga arki karaa qaybta tuubada. Tuubada noocaan ah waxay ka dhigi kartaa dareeraha qulqulaya derbiyada dhismayaashan qalalaasaha ah, waxay soo saaraan meelaha socodka socodka, waxayna sameeyaan wareegyo leh xoog iyo cabbir kala duwan. Waa wareegyadan kuwaas oo beddela qaabdhismeedka qulqulka dareeraha oo kordhiya qulqulka u dhow derbiga, si loo hagaajiyo isku-dhafka filimka kulaylka kuleylka ee dareeraha iyo derbiga.

a. jeexdin jeexdin jeexdin tube jeexdin jeexdin tube waa in la rogo jeexdin toosan ama jeexdin spiral leh garoon gaar ah iyo qoto dheer ka baxsan tuubada wareeg ah sida shuruudaha design, iyo samaynta feeraha jiifsan soo baxay ama feeraha spiral on derbiga gudaha ee tuubada, sida ku cad sawirka 1. jeexdin on derbiga dibadda iyo soo bixidda on tuubada ee gidaarka gudaha ee dareeraha labada dhinac ee isku midka ah ee dareeraha gudaha ee dareeraha gudaha labada dhinac. waqti. Waxay si gaar ah ugu habboon tahay xoojinta kulaylka wareejinta dareeraha hal-waji ee tuubada iyo kor u qaadista uumiga iyo filimka dareeraha ah ee karkaraya wareejinta kulaylka ee dareeraha ka baxsan tuubada kuleylka kulaylka.

b. Tuubbada jeexan ee spiral waxay leedahay hal baas iyo baas badan iyo noocyo kale. Ka dib marka la sameeyo, waxaa jira jeexdin leh xagal wareegsan oo ka baxsan tuubada jeexjeexa, waxaana jira feeraha convex u dhigma ee tuubada. Godka wareegsan waa inuusan noqon mid qoto dheer. Qoto dheer ee jeexdintu waa, caabbinta qulqulka weyn, weynaanta xagasha wareega, iyo weynaanta filimka kulaylka wareejinta ee tuubada jeexan. Haddii dheecaanku ku wareego jeexdin, tirada duntu waxay saameyn yar ku leedahay wareejinta kulaylka.

c. Tuubbada jeexjeexan ee iskutallaabta ah waxaa lagu sameeyaa isgoysyada isdhaafka ah ee isbeddelka joogtada ah. Bannaanka tuubada waa jeex-jeexan oo isku xira dhidibka biibiile ee 90 °, iyo gudaha tuubada waa feeraha qalloocan. Ka dib marka qulqulka dareeruhu uu dhex maro feeraha convex ee tuubada, ma soo saaro qulqulka wareega, laakiin waxay soo saartaa kooxaha vortex-ka ee qaybta oo dhan, si loo xoojiyo wareejinta kulaylka. Tuubbada dunta iskutallaabta ah ayaa sidoo kale saameyn weyn ku leh filimka karkaraya wareejinta kulaylka ee dareeraha tuubada, taas oo kordhin karta isku-dhafka kulaylka karkarinta 3-8 jeer.
