Grooved pipe imhando yepombi ine groove mushure mekukunguruka. Zvakajairwa: denderedzwa grooved pombi, oval grooved pombi, etc. iyo inonzi grooved pombi nokuti iri pachena groove inogona kuonekwa muchikamu chepombi. Rudzi urwu rwepombi runogona kuita kuti mvura ifambe nemumadziro ezvimiro zvenyonganyonga iyi, ibudise nzvimbo dzekuparadzanisa dzinoyerera, uye igadzire mavhoti ane simba nehukuru hwakasiyana. Ndiwo mavhoti aya anoshandura kuyerera kwemvura uye kuwedzera mhirizhonga padhuze nemadziro, kuitira kuvandudza iyo convective kupisa kupisa firimu coefficient yemvura uye madziro.

a. Rolling groove tube rolling groove chubhu ndeyekukungurutsa gorizone kana spiral groove neimwe pitch uye kudzika kubva kunze kwechubhu yedenderedzwa zvinoenderana nezvinodiwa nedhizaini, uye kugadzira mbabvu yakachinjika yakachinjika kana mbabvu yakatenderera pamadziro emukati echubhu. , sezvinoratidzwa muMufananidzo 1. Iyo groove pamadziro ekunze uye kuputika pamadziro emukati wepombi inogona kuwedzera kupisa kwemvura yemvura kumativi ose epombi panguva imwe chete. Inonyanya kukodzera kusimbisa kupisa kwekupisa kwe-single-phase fluid mupombi uye kuwedzera mhepo inoputika uye firimu remvura rinopisa kupisa kwemvura kunze kwepombi mune inopisa kupisa.

b. Spiral grooved pombi ine imwe pass uye yakawanda pass spiral uye mamwe marudzi. Mushure mekugadzirwa, pane gorofu rine imwe kona inotenderera kunze kwepombi yegororo, uye pane mbabvu dzinoenderana mupombi. Iyo spiral groove haifanirwe kunge yakadzika zvakanyanya. Iyo yakadzika groove iri, iyo yakakura kuramba kuyerera, iyo yakakura spiral angle, uye yakakura kupisa kupisa firimu coefficient ye grooved chubhu. Kana iyo mvura ichigona kutenderera mugero, nhamba yeshinda haina mhedzisiro yekupisa kupisa.

c. Muchinjikwa grooved pombi inoumbwa nekushanduka-shanduka-chikamu chinoramba chichikunguruka. Kunze kwepombi igororo rakachinjika rinopindirana neakisi yepombi pa90 °, uye mukati mepombi mune mbabvu yakachinjika. Mushure mekunge mvura inoyerera ichipfuura nepakati pembabvu yemupombi, haiburitse spiral kuyerera, asi inoburitsa axial vortex mapoka pamwe nechikamu chose, kuitira kusimbisa kuchinjisa kupisa. Muchinjikwa wakarukwa chubhu inewo simba guru rekusimbisa pafirimu iri kufashaidza kupisa kufambiswa kwemvura muchubhu, iyo inogona kuwedzera kufashaira kwekutamisa kupisa coefficient ne3-8 nguva.
