Sulurry pump inviscid flow solution
Tekinoloje ya Slurry inviscid flow ikuphatikiza izi: (a) theory of the two dimensional cascade flow theory;(2) njira ziwiri-dimensional ndi zitatu zomwe zingathe kuyenda;(3) awiri-dimensional quasi-atatu-dimensional, mtsinje ntchito equations;(4) ma equation awiri a dimensional ndi atatu-dimensional Euler;(5) chiphunzitso chothamanga chachiwiri.
Slurry-dimensional cascade theory ndi njira yosavuta, yomwe imakhala yothandiza kwambiri pakukakamiza komanso kulosera zachuma.Komanso yerekezerani malo otaya pang'ono.Chifukwa chake, popeza Pulofesa Wu Zhonghua adaganiza zopatsa nkhope ziwiri zotsutsana za chiphunzitso chonse chakuyenda, kuwerengera kwamayendedwe atatu-atatu kunapanga zotsatira zambiri zokopa maso.Pakalipano, gawo la mafakitale lakhala likugwiritsidwa ntchito kwambiri.Katsanits ndi Meokally, Krimmerman ndi Adler apanga ukadaulo uwu.Zapakhomo Xin Xiao Kang Jiang Jinliang anapanga iliyonse Dingzhun orthogonal pamwamba njira, Wu Yulin, etc. ntchito njira imeneyi kuwerengera wosanganiza slurry mpope hayidiroliki makina.
M'zaka za m'ma 1980, ma computing osakhazikika adatembenuza ma equation a Euler, omwe ali chifukwa cha maulendo atatu omwe amatha kuyenda komanso njira zina sizingaganizire za whirlpool zomwe zingaperekedwe ku zotayika zonse za viscous zomwe zinatayika.
M'zaka zaposachedwapa, atatu-dimensional sanali zomata miyalapompa madzimakompyuta akakhwima, anthu ochulukirachulukira akutembenukira ku ntchito makamaka amaphatikiza njira yowerengera malire a viscous flow, Navier-Stokes equations sectional chemical method ndi Navier-Stokes equations.
Njira zomwe zimagwiritsidwa ntchito nthawi zambiri zothetsa malire ndi njira zophatikizira komanso njira zosiyanitsira malire.Popeza chitukuko cha luso kompyuta, kenako pang'onopang'ono m'malo wakale.Pampu ya Arakawa et axial yokhala ndi njira yofunikira yothetsera kusanjikiza kwa malire azithunzi zitatu pa tsamba;Lakshminarayana kaphatikizidwe njira monga kugwiritsa ntchito chopangira chopangira turbine tsamba ndi impeller opiamu dimensional m'mphepete kalasi kuyenda, ndi koyefiya wa mikangano pakati padziko kudzera kumayambiriro njira kusinthidwa amaganizira kasinthasintha, kupindika ndi kuthamanga gradient zotsatira panobe.Kutumiza kwa Vasta kwa osagwirizana ndi orthogonal kumagwirizanitsa ma equation osanjikiza amalire ndi njira yothetsera;Anderson wapanga zosintha zina, pogwiritsa ntchito kukakamiza koyezera komanso pamwamba pa ma equation a Euler,Njira zogwiritsira ntchito pampu ya slurryjambulani malire osanjikiza akunja kwa malire, ndiyeno muwerengere kasinthasintha kawongoleredwe kakuthamanga kozungulira.Chotsatira cha njira yofananira yofananira imaphatikizidwa ndi kuyesa, Wu Yulin, kuwerengera makina osungira madzi pamikhalidwe yosiyana, kulosera kulekanitsidwa kwanuko kwa chowongolera chotsogola ndi chotsatira.
Gravel mpope olimba-zamadzimadzi osakaniza umayenda mu chubu lalifupi kuchokera suction impeller, particles olimba mu ma radial ndi axial kayendedwe kwa chivundikiro kumbuyo, chifukwa inertia akuchita kumbuyo chivundikiro anagunda ndi kumbuyo chivundikirocho kupirira zotsatira za tinthu zikuluzikulu. mphamvu, kuchuluka kwa matupi ndi misozi.Zambiri mwa tinthu tokhazikika pafupi ndi tsamba kuchokera ku tsamba lotsogolera la tsamba kulowa m'mphepete mwa tsamba, ndipo gawo la tsamba pafupi ndi kumbuyo kwa tinthu tomwe timayenda.Morphology kuchokera ku mavalidwe a impeller ndi zotsatira za abrasion, kuchokera kutsogolo kwa m'mphepete kumbuyo kwa tsamba kumavala zowonjezera.Kupopa chisakanizo cha tinthu tating'onoting'ono tating'onoting'ono, njira yopita kwa tsamba ndi njira yopindika yamtundu wa tsamba lopindika lofanana ndi nkhope ya tsamba la mavalidwe amavutika kwambiri kuposa masamba kumbuyo.
Tinthu tating'onoting'ono tomwe timatulutsa tinthu tating'onoting'ono tomwe timatuluka pa tsambalo, pomwe tinthu tating'onoting'ono totulukamo tinthu tating'onoting'ono tomwe timayenda.Pafupi ndi mbali yakunja ya malo osakanikirana a impeller,API muyezo zikutanthauzatinthu tating'onoting'ono timakhala ndi liwiro laling'ono la radial.Kusakaniza pang'onopang'ono kutulutsidwa kuchokera ku chopondera ndi mkati zotumphukira khoma la otaya mpope, olimba particles pang'onopang'ono kuchuluka, ndi impeller tsamba kubwereketsa m'mphepete kupirira chilly osakaniza udindo tsamba kubwereketsa m'mphepete mwa tsamba kuvala mbali zoipa.
