High Speed Flow Simulation in Fuel Injector Nozzles (part 6)
Qhov me me, kev kub ceev thiab lub sij hawm luv luv ua rau nws nyuaj heev los kawm txog tus cwj pwm sim.Kev ua qauv cavitation tuaj yeem pab tau hauv kev simulating ntws hauv qhov loj me me injector nozzles thiab kawm cov yam ntxwv ntawm lub nozzle, uas cuam tshuam rau qhov ntws hauv lub nozzle.
Kev tsim kho ntawm ib qho kev simulation ntawm cavitating injector nozzles pib nrog cov kev xav ntawm cov phenomenon uas yuav suav nrog thiab uas yuav tsis saib xyuas [12].Txog rau tam sim no, tsis tau muaj kev pom zoo txog seb nws puas tuaj yeem xav tias me me, high-speed cavitating nozzles nyob rau hauv thermal lossis inertial equilibrium.Yog hais tias ib tug xav hais tias lub nozzle nyob rau hauv thermal equilibrium, ces yuav tsis muaj kev ncua tseem ceeb nyob rau hauv npuas loj hlob los yog vau vim los ntawm tshav kub hloov.Thaum tshav kub kub hloov yog infinitely ceev thiab inertial cuam tshuam txwv theem hloov.Lub assumption ntawm inertial equilibrium txhais tau hais tias ob theem muaj negligible swb tshaj tawm.
Xwb, nyob rau qib sub-grid scale, ib tug kuj tseem yuav xav txog qhov ua tau ntawm cov npuas me me uas nws qhov loj me teb rau cov kev hloov hauv siab.Qhov kev xav ntau haiv neeg no ua rau muaj ntau yam kev ua qauv qhia.Simulations ntawm cavitating atomizer nozzles invariably yuav tsum tau simplifying kev xav.Cov kev xav no yuav tsum muaj txaus los ua kom cov teeb meem tuaj yeem daws tau yam tsis muaj qhov tsis raug.Lub hom phiaj ntawm txoj haujlwm no yog tsim kom muaj peb-dimensional CFD solver los simulate ntws nyob rau hauv ib tug me me, high-speed cavitating nozzle siv homogeneous equilibrium qauv (HEM).HEM siv rau hauv txoj haujlwm no txuas ntxiv tus qauv piav qhia los ntawm Schmidt li al.[1,2] nyob rau hauv multidimensional thiab parallelized moj khaum.Tus qauv txuas ntxiv mus simulate cov teebmeem tsis-linear ntawm cov theem ntshiab hauv kev ntws thiab cov lej sib txawv ntawm kev ua haujlwm los ntawm Schmidt li al.
