Isisombululo se-pumpry pumpscid
Itekhnoloji yokuhamba ye-infurry yenvourcid ibandakanya oku kulandelayo: (a) ithiyori ye-Cascade ye-Cascade; (2) isisombululo esinemilinganiselo emibini kunye neyemilinganiselo emithathu yokuhamba; . . (5) ithiyori yokuhamba kwesibini.
Ithiyori ye-Cascade ye-Cascade yindlela elula, esebenza kakhulu kuxinzelelo nakwindlela yoqoqosho. Qikelela uqikelelo lwendawo yokuhamba kancinci kancinci. Ke ngoko, ekubeni uNjingalwazi Wu Zhonghua waqala ukunika obu buso lunye ngokuthe gabalala lwethiyori ngokubanzi yokuhamba, kubalo lwe-quasi-ezintathu ezihamba ngeendlela ezininzi ezibambisa ngamehlo. Okwangoku, icandelo lemizi-mveliso lisetyenziswe ngokubanzi. I-KATANSANITS kunye ne-Meuksm, iKrimmerman noAdler baye bakhulisa le teknoloji. I-xian xiao kang jiang jiniang yenza nayiphi na indlela ye-Dingzhun ye-Orthogonal, i-YU YULIN, njl njl.
Ngeminyaka yee-1980s, i-compystream enganamathela kwikhompyuter iguqule i-EULER Equations, nto leyo ebangelwa kukuhamba okunokubakho okunokubakho kunye nezinye iindlela ezingenakunikwa ilahleko ye-Vircool enokunikwa ilahleko.
Kwiminyaka yakutshanje, imilinganiselo emithathu enganamathelaImpompo yelayitaUkupaka iKhompyuter, ngakumbi abantu abaninzi baguqukele emsebenzini ikakhulu babandakanya umda we-vismoint wendlela yokuhamba, i-Navier-I-Trier-Stots Equices Equictions kunye ne-Navier -toier -toy -toy-stokes.
Iindlela ezisetyenzisiweyo ezisetyenzisiweyo zomda wokucombulula yindlela yokudibanisa kwaye igqityiwe umahluko omkhulu. Ukususela kuphuhliso lwetekhnoloji yeKhompyutha, ngokuthe ngcembe emva kwexesha yathatha indawo yangaphambili. I-Arakawa i-Axial Pump indlela yokudibanisa ukusombulula ungqingo lwe-purestment tuers kwibala; Indlela yokudibanisa iLakshminarayana efana nokusebenzisa i-turbine blade kunye ne-Impeller Apium Diment Fitring, i-coander dimer, i-coander yokuhamba-hamba phakathi kwendlela eguqulweyo ithathela ingqalelo ekujikelezisweni, i-curvature kunye nefokoxiyo. Ukukhuphela i-vasta yokuthumela ngaphandle kokujikeleza kwe-orthogonal kulungelelanisa i-theatri ehambelana ne-anthente kunye nendlela yesisombululo; UAnderson waqhuba uphuculo, esebenzisa uxinzelelo olulinganisiweyo kunye nomphezulu we-EULEREENT,Amanyathelo okusebenza kwempompo ye-slirryZoba imida yogcino lwemeko yomda, kwaye ubhale ujikelezo lwe-Cascade ukuhamba kwendawo yoxinzelelo. Isiphumo sendlela yomahluko ogqityiweyo idityaniswe novavanyo, i-Wu Yulin, ibala oomatshini bokugcina amanzi kwiimeko zoyilo olungeloyilo, babalaselisa ukwahlulwa kwendawo ye-Impleller ekhokelayo kunye nomphetho we-impeller.
I-Gravel Pummp yokuhamba-hamba ihamba kwityhubhu emfutshane evela kwi-Implermer ye-radial kunye ne-axial kwi-Inrial Compt, ngenxa ye-Inertia kwi-Inrial Privar kwi-Privanes enkulu yokumelana nesiphumo samasuntswana aphezulu Njani, ukunxiba kunye nokukrazula. Uninzi lwamasuntswana aqinileyo kufutshane ne-blade ukusuka kwibala le-blade elikhokelela kwi-blade kwisitishi sokuhamba, kunye nenxalenye yebala ecaleni kwamasuntsu. I-morphology evela kwi-Impleller i-Impler kunye neziphumo ze-arasion, ukusuka kumda ophambili womda ongasemva we-blade welow unxibe izandiso. Ukupeyimba umxube wamasuntswana amahle, ijelo lokuhamba kwebala kunye nohlobo lokuhamba ngebala lokuhamba kwe-curvature efana ne-curvature efana ne-blade i-blade ibuyile.
I-Gravel Pump Asundussungus iphuma kwibala, apho kumasuntswana amancinci aphuma kwi-engile encinci kwindlela yokuhamba. Kufutshane ne-periphery engaphandle yomxube we-IMPORT emfazwe,I-API esemgangathweni ithethaAmasuntswana amahle anendawo encinci yeralicial. Umxube ngokuthe ngcembe wakhutshwa kancinci kwi-impler kunye nodonga lwempungutye ye-pirtheral yokuhamba kwempompo, amasuntswana aqinileyo anyuka ngokuthe ngcembe, umphetho we-veler blade umda we-Blade
