FAQ
HIGH SPEED FLOW SIMULATION IN FUEL INJECTOR NOZZLES (Part 1)
Atomization ntawm roj yog qhov tseem ceeb hauv kev tswj cov combustion hauv lub cav ncaj qha. Tswj combustion pab txo emissions thiab boosting efficiency. Cavitation yog ib qho ntawm cov yam tseem ceeb uas cuam tshuam rau qhov xwm ntawm cov tshuaj tsuag hauv chav combustion. Hom roj injector nozzles yog me me thiab ua haujlwm ntawm qhov kub siab heev, uas txwv txoj kev kawm ntawm tus cwj pwm hauv lub nozzle. Lub sijhawm thiab qhov ntev ntawm qhov ntsuas ntxiv txwv qhov kev sim ntawm cov roj injector nozzle. Simulating cavitation nyob rau hauv ib tug roj injector yuav pab kom nkag siab txog qhov tshwm sim thiab yuav pab nyob rau hauv kev loj hlob ntxiv.
Kev tsim kho ntawm ib qho kev simulation ntawm cavitating injector nozzles pib nrog cov kev xav ntawm cov phenomena uas yuav suav nrog thiab uas yuav tsis saib xyuas. 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.
Qhov kev xav ntau haiv neeg no ua rau muaj ntau yam kev ua qauv qhia. Yog hais tias ib tug xav tias lub nozzle nyob rau hauv thermal equilibrium, ces yuav tsis muaj kev ncua tseem ceeb Vi 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 xav txog qhov ua tau ntawm cov npuas me me uas nws qhov loj me teb rau cov kev hloov hauv siab. Schmidt et al. [1,2] tau tsim ob qhov sib txawv ntawm qhov sib npaug ntawm cov qauv sib npaug uas tau npaj rau kev simulating me me, kev kub ceev nozzle ntws. Lub HEM siv qhov kev xav ntawm thermal equilibrium los simulate cavitation. Nws xav tias ob-theem ntws hauv lub nozzle hauv homogeneous sib xyaw ntawm vapor thiab kua.
Txoj haujlwm no nthuav tawm cov kev simulation ntawm lub siab ceev nozzle, siv HEM rau cavitation, nyob rau hauv ntau qhov sib txawv thiab sib npaug. Tus qauv yog txuas ntxiv mus simulate qhov tsis-linear cuam tshuam ntawm cov theem ntshiab hauv kev khiav thiab cov lej mus kom ze tau hloov kho kom ua tiav qhov tshwm sim ruaj khov hauv ntau lub hauv paus.
