Umbhobho ogobileyo luhlobo lombhobho one-groove emva kokuqengqeleka. Okuqhelekileyo: umbhobho ogobileyo ojikelezayo, umbhobho ogobileyo ojikelezayo, njl. ubizwa ngokuba ngumbhobho ogobileyo kuba umbhobho ocacileyo unokubonwa kwicandelo lombhobho. Olu hlobo lombhobho lunokwenza ulwelo luhambe eludongeni lwezakhiwo ze-turbulence, luvelise iindawo zokwahlula ukuhamba komoya, kwaye lwenze ii-vortices ezinobukhulu obahlukeneyo. Zii-vortices ezitshintsha isakhiwo sokuhamba komoya wo ...

a. Ityhubhu ye-rolling groove ityhubhu ye-rolling groove kukuqengqa umngxuma othe tyaba okanye umngxuma ojikelezayo onobubanzi obuthile kunye nobunzulu obuvela ngaphandle kwetyhubhu ejikelezayo ngokweemfuno zoyilo, kwaye yenze umngxuma othe tyaba ophumayo okanye umngxuma ojikelezayo eludongeni lwangaphakathi lwetyhubhu, njengoko kubonisiwe kuMfanekiso 1. Umngxuma eludongeni lwangaphandle kunye nokugquma eludongeni lwangaphakathi lwetyhubhu kunokunyusa ukudluliselwa kobushushu bolwelo kumacala omabini etyhubhu ngaxeshanye. Ifanelekile ngokukodwa ekuqiniseni ukudluliselwa kobushushu kolwelo lwesigaba esinye kumbhobho kunye nokuphucula ukufuma komphunga kunye nokudluliselwa kobushushu obubilayo kwifilimu yolwelo ngaphandle kombhobho kwi-heat exchanger.

b. Umbhobho ojikelezileyo ojikelezayo une-single pass kunye ne-multi pass spiral kunye nezinye iintlobo. Emva kokwenziwa, kukho umngxuma one-angle ethile ejikelezayo ngaphandle kombhobho ojikelezileyo, kwaye kukho iimbambo ezingqukuva ezihambelanayo kumbhobho. Umngxuma ojikelezileyo akufuneki ube nzulu kakhulu. Okukhona umngxuma unzulu, kokukhona ukumelana nokuhamba kwamanzi kukhulu, kokukhona i-angle ejikelezayo inkulu, kwaye kokukhona i-coefficient enkulu yefilimu yokudlulisa ubushushu yombhobho ojikeleziweyo. Ukuba ulwelo lunokujikeleza ecaleni komngxuma, inani lemisonto alinampembelelo ingako ekudluliseleni ubushushu.

c. Umbhobho ojikelezileyo wenziwe ngokuqengqeleka okuqhubekayo okuguquguqukayo. Umphandle wombhobho ngumngxuma onqamlezayo odibanisa i-axis yombhobho kwi-90 °, kwaye umngaphakathi wombhobho ngumngxuma ojikelezileyo ojikelezileyo. Emva kokuba ukuhamba kolwelo kudlule kumbhobho ojikelezileyo kumbhobho, akuvelisanga ukuhamba okujikelezayo, kodwa kuvelisa amaqela e-axial vortex kulo lonke icandelo, ukuze komelezwe ukudluliselwa kobushushu. Umbhobho ojikelezileyo unefuthe elikhulu lokuqinisa ukudluliselwa kobushushu obubilayo kwifilimu yombhobho, okunokunyusa i-coefficient yokudluliselwa kobushushu obubilayo ngamaxesha ama-3-8.
