Impompo eludaka isisombululo se-inviscid flow
Itekhnoloji ye-slurry inviscid flow technology ibandakanya oku kulandelayo: (a) ithiyori yokuqukuqela okumacala mabini;(2) isisombululo sokuqukuqela okunokubakho kumacala amabini kunye nantathu;(3) i-two-dimensional quasi-three-dimensional, i-stream function equations;(4) i-equations ye-Euler ene-dimensional ne-three-dimensional;(5) ithiyori yokuhamba kwesibini.
Ithiyori ye-Slurry-dimensional cascade yindlela elula, esebenza kakhulu kuxinzelelo kunye noqikelelo lwezoqoqosho.Qikelela ngakumbi ibala lokuhamba ngaphantsi kancinci.Ke ngoko, okoko uNjingalwazi uWu Zhonghua ecebise ukunika ubuso obubini obuchaseneyo bethiyori ngokubanzi yokuhamba, ukubala komqukuqelo omacala amathathu kwenze iziphumo ezininzi ezitsala amehlo.Okwangoku, icandelo lezoshishino lisetyenziswe ngokubanzi.I-Katsanits kunye ne-Meokally, i-Krimmerman kunye ne-Adler baye baphuhlisa le teknoloji.I-Domestic Xin Xiao Kang Jiang Jinliang yenza nayiphi na indlela ye-Dingzhun orthogonal surface, Wu Yulin, njl.
Ngeminyaka yoo-1980, i-non-sticky computing mainstream yajika iiequations ze-Euler, ezibangelwa kukuqukuqela okunokubakho kwe-dimensional-dimensional ezintathu kunye nezinye iindlela azikwazi ukuqwalasela i-whirlpool effect enokunikezelwa kuyo yonke ilahleko ye-viscous ilahlekelwe amaxabiso elahleko.
Kwiminyaka yakutshanje, igrabile enamacala amathathu angancamathelangaimpompo eludakaI-computing ikhula, abantu abaninzi baguqukela emsebenzini ikakhulu babandakanya indlela yokubala ye-border layer viscous flow, i-Navier-Stokes equations yecandelo lemichiza indlela kunye ne-Navier-Stokes equations.
Iindlela eziqhelekileyo ezisetyenziswayo zokusombulula umda ziindlela ezidityanisiweyo kunye neendlela zomahluko onomda.Ukususela ekuphuhlisweni kobuchwepheshe bekhompyutha, kamva ngokuthe ngcembe ithathe indawo yangaphambili.Impompo ye-Arakawa et axial enendlela edibeneyo yokusombulula umaleko womda onezidubedube-ntathu kwincakuba;Indlela yokuhlanganisa ye-Lakshminarayana efana nokusebenzisa iblade ye-iturbine kunye ne-impeller ye-opium edge yeklasi yokuhambahamba, i-coefficient of friction phakathi komphezulu ngokwaziswa kwendlela elungisiweyo ithathela ingqalelo kujikelezo, igophe kunye nesiphumo sokuthamba koxinzelelo okwangoku.Ukuthunyelwa kwamanye amazwe kweVasta ye-non-orthogonal rotation ilungelelanisa i-equations boundary layer equations kunye nesisombululo sendlela;U-Anderson wenze uphuculo oluthile, esebenzisa uxinzelelo olulinganisiweyo kunye nomphezulu we-equations ye-Euler,Amanyathelo okusebenza kwempompo eludakazoba umaleko womda iimeko zomda wangaphandle, uze ubale ukujikeleza okujikelezayo ukuhamba komphezulu woxinzelelo.Isiphumo sendlela yomehluko ogqityiweyo idityaniswe novavanyo, iWu Yulin, ukubala oomatshini bokugcina amanzi kwiimeko zoyilo olungekhoyo, baqikelele ukwahlulwa kwendawo ye-impeller ehamba phambili kunye ne-trailing edge.
Impompo yegrabile umxube oqinileyo wolwelo uqukuqela kwityhubhu emfutshane ukusuka kwi-impeller yokufunxa, amasuntswana aqinileyo kwi-radial kunye ne-axial intshukumo ukuya kwisigqubuthelo esingasemva, ngenxa ye-inertia esebenza kwikhava yangasemva ingqubane nesigqubuthelo esingasemva ukumelana nefuthe lamasuntswana amakhulu. amandla, ukunyuka nokukrala.Uninzi lweengqungquthela eziqinileyo kufuphi ne-blade ukusuka kwi-blade ehamba phambili ebusweni be-blade kwi-flow channel, kunye nenxalenye ye-blade kufuphi nomva weengqungquthela kwi-flow path.I-Morphology evela kwi-impeller wear kunye neziphumo ze-abrasion, ukusuka kumda okhokelayo wecala elingasemva le-blade linxiba izandiso.Ukumpompa umxube wamasuntswana acolekileyo, umjelo wokuhamba wencakuba kunye nohlobo lwencakuba eshukumayo kwindlela egophe ngayo efana nencakuba yobuso bokunxitywa ihlupheke kakhulu kuneencakuba ngasemva.
Ipompo yegrabile amasuntswana aqinileyo aphuma kwincakuba, apho kumasuntswana amancinane eengile yokuphuma ecaleni kwendlela yokuhamba.Ikufuphi nomda wangaphandle wendawo yokuhamba komxube we-impeller,API umgangatho kuthethaamasuntswana amahle anesantya esincinci seradial.Umxube okhutshwa kancinci kwi-impeller kunye nodonga lwangaphakathi lweperipheral lokuhamba kwempompo, amasuntswana aqinileyo anyuka ngokuthe ngcembe, i-impeller blade outlet edge imelana nomxube obandayo wendima yeblade yokuphuma komphetho wencakuba ukunxiba ezona ndawo zimbi.
