Gas Turbine Diffuser

Lub luag haujlwm tseem ceeb thiab cov yam ntxwv ntawm cov roj turbine diffuser suav nrog:

Cov roj turbine diffuser, tseem hu ua diffuser duct, yog ib qho tseem ceeb ntawm cov roj turbine cav uas pab ua kom cov kev ua tau zoo ntawm lub cav cua compression txheej txheem. Nws lub luag haujlwm tseem ceeb yog ua kom qeeb thiab nthuav dav lub siab-ceev, compressed cua tawm ntawm compressor seem ua ntej nws nkag mus rau hauv lub combustion chamber. Qhov no nthuav thiab deceleration ntawm airflow yog ib qho tseem ceeb rau ntau yam:

Pressure Recovery: Lub diffuser pab kom rov zoo li qub siab nyob rau hauv cov cua ntws. Cov cua kub ceev tawm ntawm lub compressor muaj lub zog kinetic, thiab lub diffuser lub diverging zoo hloov lub zog kinetic rov qab mus rau qhov zoo li qub, uas muaj txiaj ntsig zoo rau combustion.

Kev txo qhov kub thiab txias: Kev nrawm nrawm ntawm huab cua hauv compressor tuaj yeem nce nws qhov kub thiab txias. Kev ua kom qis qis hauv huab cua hauv diffuser txo nws qhov kub, uas yog qhov tseem ceeb los tiv thaiv overheating hauv chav combustion chamber.

combustion Stability: qeeb qeeb, qis-kub cua yog yooj yim rau tov nrog roj thiab ua kom ruaj khov thiab muaj txiaj ntsig combustion.

Kev tsim cov roj turbine diffuser yog ua tib zoo tsim kom ua tiav cov hom phiaj no. Nws feem ntau muaj qhov sib txawv ntawm cov kav dej uas ua tib zoo contoured nto kom txo qis kev sib cais, siab poob, thiab turbulence. Qhov kev tsim no pab ua kom lub siab rov qab zoo dua thiab txhim kho tag nrho kev ua tau zoo thiab kev ua haujlwm ntawm lub cav roj turbine.

Hauv cov ntsiab lus, cov roj turbine diffuser yog cov khoom tseem ceeb uas npaj cov cua compressor los ntawm compressor kom muaj txiaj ntsig zoo thiab ruaj khov combustion hauv lub cav roj turbine. Nws ua lub luag haujlwm tseem ceeb hauv kev txhim kho lub siab rov qab, txo qhov kub thiab txias, thiab txhim kho kev ua kom combustion efficiency.
