Compressible flow yog ceg ntawm cov tshuab ua kua dej uas cuam tshuam nrog cov ntws muaj kev hloov pauv tseem ceeb hauv cov kua dej. Thaum tag nrho cov ntws yog compressible, ntws feem ntau yog kho tsis tau thaum tus lej Mach tsawg dua 0.3.
piv txwv ntawm cov kua compressible yog dab tsi?
Vapors thiab Gases Cov dej ntws tawm xws li roj, vapor, chav, thiab lwm yam., suav nrog feem ntau tib yam li cov kua lossis tsis yog -compressible fluids.
Nws yog compressible fluid?
Vim gas yog cov kua compressible, cov roj compressed yuav tso tawm lub zog (slow down pressure depletion) thaum lub zog siab txo.
Koj txhais li cas los ntawm compressible kua?
Definition. Compressible Fluid: Compressible kua yog ib qho teeb meem uas tuaj yeem compressed nrog daim ntawv thov ntawm lub siab sab nraud. Incompressible Fluid: Incompressible fluid yog ib qho teeb meem uas tsis tuaj yeem compressed nrog kev siv lub siab sab nraud.
Dab tsi yog compressible thiab incompressible fluid?
Cov cuab yeej ntawm kev hloov pauv yog hu ua compressibility thiab cov kua uas nws ntim hloov pauv hu ua compressible fluid. Ntawm qhov tod tes, cov kua dej incompressible yog cov kua uas tsis compressed lossis nthuav dav, thiab nws qhov ntim ib txwm nyob tas li. Qhov tseeb tiag, cov kua dej tsis sib haum tsis muaj nyob.
