Qhov sib txawv tseem ceeb ntawm cov nplaim hluav taws kub ceev thiab qhov kub ceev yog qhov hluav taws kub ceev sawv cev rau qhov nrawm ntawm kev mus ncig ntawm cov nplaim taws los ntawm qhov chaw siv kiag li, qhov kub kub sawv cev rau tus nqi ntawm kev txav ntawm cov tshuaj reactants rau hauv daim ntawv tshuaj tiv thaiv los ntawm ib qho lub hauv paus ntsiab lus uas nyob rau ntawm lub nplaim taws pem hauv ntej.

Nplaim taws nrawm thiab qhov nrawm nrawm yog ob nqe lus sib txawv uas muaj txiaj ntsig zoo hauv kev tshawb fawb txog cov nplaim taws. Nplaim taws ceev yog tus nqi ntawm kev nthuav dav ntawm cov nplaim taws pem hauv ntej hauv cov tshuaj tiv thaiv combustion. Qhov hluav taws kub kub, ntawm qhov tod tes, yog qhov ceev ntawm cov nplaim taws hauv ntej propagates txheeb ze rau cov roj uas tsis tau hlawv.

nplaim taws ceev yog dab tsi?

Nplaim taws ceev yog tus nqi ntawm kev nthuav dav ntawm cov nplaim taws pem hauv ntej hauv cov tshuaj tiv thaiv combustion. Feem ntau, nplaim taws propagates spherically, thiab peb muaj peev xwm muab lub npe nrov tshaj tawm ntawm radial nplaim propagation li nplaim taws ceev. Feem ntau, nplaim taws ceev sawv cev rau qhov ceev ntawm kev mus ncig ntawm cov nplaim taws los ntawm qhov chaw siv kiag li. Ntawm qhov tod tes, qhov hluav taws kub kub sawv cev rau tus nqi txav ntawm cov tshuaj reactants mus rau hauv daim ntawv tshuaj tiv thaiv los ntawm ib qho chaw siv hauv zos uas nyob rau ntawm cov nplaim taws pem hauv ntej (Muaj, cov tshuaj reactants feem ntau yog cov roj tsis muaj hluav taws xob thaum cov ntawv tshuaj tiv thaiv yog hais txog cov nplaim taws pem hauv ntej).

Thaum xav txog lub cav combustion sab hauv, peb tuaj yeem piav qhia cov nplaim taws ceev raws li cov cuab yeej uas tuaj yeem txiav txim siab lub peev xwm ntawm lub cav kom dhau los tswj kev sib tsoo yam tsis muaj qhov tawg. Peb tuaj yeem siv cov nplaim taws nrawm nrog rau cov nplaim taws kub hnyiab rau kev txiav txim siab ntawm lub cav ua haujlwm. Txawm li cas los xij, nplaim taws ceev tsis yog lub tshuab hluav taws xob tiag tiag. Piv txwv li, 12: 1 compression ratio roj av cav uas ua tau zoo ntawm 1500 rpm nyhav kom muaj nplaim taws ceev ntawm ib ncig ntawm 16.5 m / s thaum lub cav zoo sib xws hydrogen nyhav yield 48.3 m / s.

Kev kub hnyiab yog dab tsi?

Kev kub nyhiab tuaj yeem piav qhia raws li qhov nrawm ntawm cov nplaim taws hauv ntej propagates txheeb ze rau cov roj uas tsis tau hlawv. Ib tug derivative ntawm lub sij hawm no yog lub laminar burning tshaj tawm, uas yuav txhais tau tias raws li qhov ceev ntawm lub laminar (planar) combustion yoj propagates txheeb ze rau lub unburnt gas sib tov uas yog ua ntej ntawm nws.

Qhov txawv ntawm nplaim taws thiab qhov kub hnyiab yog dab tsi?

Nplaim taws nrawm thiab qhov nrawm nrawm yog ob nqe lus sib txawv uas muaj txiaj ntsig zoo hauv kev tshawb fawb txog cov nplaim taws. Qhov sib txawv tseem ceeb ntawm cov nplaim hluav taws kub thiab qhov kub ceev yog qhov hluav taws kub ceev sawv cev rau qhov ceev ceev ntawm kev mus ncig ntawm cov nplaim taws los ntawm qhov chaw siv kiag li, qhov kub kub sawv cev rau tus nqi ntawm kev txav ntawm cov tshuaj reactants mus rau hauv daim ntawv tshuaj tiv thaiv los ntawm lub zos siv taw tes uas yog. nyob rau ntawm nplaim taws pem hauv ntej.

Cov lus hauv qab no qhia txog qhov sib txawv ntawm qhov sib txawv ntawm cov nplaim taws ceev thiab qhov nrawm nrawm.

Summary – Nplaim Ceev vs Hla Hlav

Nplaim taws ceev yog tus nqi ntawm kev nthuav dav ntawm cov nplaim taws pem hauv ntej hauv cov tshuaj tiv thaiv combustion. Kev kub ceev yog qhov ceev ntawm qhov hluav taws kub hauv ntej propagates txheeb ze rau cov roj uas tsis tau hlawv. Qhov sib txawv tseem ceeb ntawm cov nplaim hluav taws kub thiab qhov kub ceev yog qhov hluav taws kub ceev sawv cev rau qhov ceev ceev ntawm kev mus ncig ntawm cov nplaim taws los ntawm qhov chaw siv kiag li, qhov kub kub sawv cev rau tus nqi ntawm kev txav ntawm cov tshuaj reactants mus rau hauv daim ntawv tshuaj tiv thaiv los ntawm lub zos siv taw tes uas yog. nyob ntawm nplaim taws pem hauv ntej.
