超声速化学反应流场迎风格式数值模拟及并行计算基于有限体积迎风格式对超声速燃烧流场进行了的数值模拟。由于超声速燃烧流场绕流的简单性,要求对多组分Euler／N～S方程求解的数值模拟方法应具有较高的计算精度及效率。本文引用帮助点方法建立了具有空间二阶精度的vanLeer迎风矢通量分裂格式,并应用于超声速燃烧流场绕流的数值模拟。化学反应为氢气／空气+反应模型,采纳考虑了化学反应特征时间的当地时间步长显式Runge—Ku维普资讯Sp20e.07TrnatnfNajgUnvriyornuisAsrnuisascisoniiestfonAeoatctoatcVo.4No.123PARALLELIZEDUPWIDNFLUXPLISTTINGCHSEMEF0RSUPERSoNREACTIICNGFLoWSoNUNSTRUCTUREDYBRIMESHESHDWagageg,WuYzanJinfniho.(lgfAeopcgneig。NUAA,2doSre,Najg,201ColeorsaeEnierne9Yuatetnin106,P.RChn)iaAbtatArleieupiuxsitngsheefuroniecilsonhyiehesprstsrc:paallzdwndfplticmorspescratngfowbrdmssieen—le.Tholxtfsprhprsnccmbsinfwsmaetncsaytsalhsleswihhgedecmpeiyoue/【e—oioutlksieesroetbiovrtihryoosrsltonfiinyfrmut—ooetlrN—qain.Hec,asaileododrvnLertpeouinadefecolimpnne/SeutsccEuoneptacn—reaeyesfuxvetpitngsheeisaihdbyitodiuxiirisintrlto,adadlcorslticmsetblsenrucngalaypontniepoainnomandeom—icDoiiehousdstonmtdeonunsrtehyieheftucurdbrdmssorobtinhiacuaifcecyThenumeiaanigghclltngefiin.rclsheewihfvesangeKutatmeseehsiplmeneotiuainofccmti-tgeRu—titpmtodimetdthesmltoombutonfows,isiln—cuigtesproihdoe/icmbsinadtenrlijcinoyrgnitecigfwsasldnhuesncyrgnaroutnhomanetfdoenoratl.Sr—oohnoilngrsteobaneompaeihiiedrfrcsyieulsartidcrdwtlmteeene.Kerywods:spesuroniombusiccton;cmiaecin;uheclratopwicme;paallztonndsherleiaiCLCnue:V213mbr1.Dounoe:cmetcdAArilD:051220)301—7teI10—1O(070—280cINTRoDUCTIoNWihheatdvlpmetohesittfseeonfypronctcehniuentewolqsihrd,moeareerh—rndmoersacarocentesesniombutonfosaefusdohuproccsilwtcie,whihsehnqucionotmosioratefhetmptntcienhyroncvhcedsgn….Ir—ehnqusipesieileinecntereyas,maahivmesneciglnyceentoratnfowsmultovebtieiainhaebenoand,nnlnotoyiwindte.aepwidfuxsitngshesetb-yp.sdubnlplticmeisa—lsenrdiuxiiroitntpaihdbyitoucngalypnsihes—ataitrlto,ateilnepoain[ndhRungeKutaie—tfv—satmenertooldwihhecmiatgeiitgaincupettheclratngcaatrsiieToipoetesm—ecihrceitctm.mrvhiultonfiiny,aatomanaiefcecfsdideopstoncmoiimehosaopeosrcueybrdmehtdidtdnuntutrdhis—as『_334.NueiarstaebtieitPC—mrcleulsroandnhecusestmadnltclyomprdltrysenaayialcaewihttoefolmieeeecs,icudnhedt—hsrmitdrfrnenligteotnexeinsbtasnnmeiaacl—unleprmetuloiurclcluatoins.wheerTVDorNNDtesheeoypcmsnsrcurdtutemehergnealue[ssaeerlysd.Coni—sdeihomplxiyoecigforngtecetfratnlws,epcalseilyntofhdoe/icmbsiniuesncainoyrgnaroutnsproiofo;tenrlijcinoyrgnjtitlwhomanetfhdoeenoaobakwadsel;ahehesixtracrtpfowndtypronceenlforndavhilthntraydognlwsaouecewihteienlhreteitra/xenlmitrlwsiincshnenletraxuefo,tsee—sroetbihhgeouinshmenh—aytsalihrsltocesonssrteybiehs。.tucurdhrdmse[ijcinratnlwntecae.netecigfoihhmbroBaentenmeiaehiusdvlpdsdohurcltcnqeeeoeihyesniardyaisrsaccntrnproceonmceerhee1GOVERNIEQUATONSNGIANDCHEMICALKINETICMoDELS11Goeniquto.vrngeains(ARC)oHfNUAAohmiao—qibimfrceclnneulruihesixtrlfowsosrcueybiypronceenalnuntutrdhrdmehe[]tnurcliuaiwihtessz,hemeiasmltonthfi—aehdoe/ioutodlsi—it-tyrgnarcmbsinmouein-nervsiaendealThescd—deaLeretgtditi.eonorrvn-e-The一mut—opeN—qutosn2DlicmonntSeainiFudtotm:SpotdbhtnlNauaceconainoia(0003onainieupreyteNaiatrlSineFudtfChnoo1421)Reevedae:2602cidt00一1—6;riinrcietevsoeevddae:27022600-—Ema:agfuaeuc—iwnjl@na.d.n
