Qhov tshwm sim yog hu ua kev sib cais ntawm ciam teb txheej. Kev sib cais yuav tshwm sim vim lub sijhawm poob ntau dhau ze ntawm phab ntsa hauv ib thaj tsam txheej sim txav mus rau hauv qab los tiv thaiv kev nce siab, piv txwv li,, uas yog hu ua qhov tsis zoo siab gradient.

Dab tsi ua rau ciam teb sib cais?

Txoj kev ciam teb sib cais thaum nws tau mus deb txaus nyob rau hauv ib qho kev tsis zoo siab gradient uas qhov ceev ntawm cov ciam teb txheej txheeb ze rau saum npoo tau nres thiab thim rov qab txoj kev Kev ntws tawm los ntawm qhov chaw, thiab siv cov ntawv eddies thiab vortices.

Vim li cas ib ntus ciam teb sib cais tom qab?

Raws li qhov nrawm nrawm ntawm qhov saum npoo yog ntau dua rau turbulent dua li laminar ntws, ua kom lub cev muaj kev cuam tshuam ntau duathaum cov ciam txheej ntws hla nws qhov chaw turbulent.… Raws li cov xwm txheej no, ciam teb txheej tuaj yeem ua tsis ruaj khov thiab cais tawm ntawm qhov chaw.

Nyob rau hauv cov xwm txheej twg ntws sib cais tshwm sim?

Kev sib cais tshwm sim thaum lub siab gradient yog qhov zoo thiab qhov nrawm nrawm yog qhov tsis zoo.

Peb tuaj yeem tiv thaiv ciam teb sib cais li cas?

Txoj kev tiv thaiv kev sib cais ntawm ciam txheej: Txhim kho lub cev zoo. Tripping ciam teb txheej los ntawm laminar mus turbulent los ntawm kev muab roughness nto. Nias lub retarded flow.
