Cov yam ntxwv geometric cov ntaub ntawv ntawm cov tub lim tsuas yog muaj cov cheeb tsam tshwj xeeb, qhov chaw porosity, qhov muab cov khoom ntim, thiab lwm yam, uas yog qhov yooj yim rau kev ntsuas cov kev ua tiav.
(1) Thaj chaw tshwj xeeb Thaj chaw thaj tsam ntawm qhov muab tub lim ib qhov ntim ntawm qhov muab tub lim hu ua qhov chaw tshwj xeeb thaj tsam, qhia raws li a, thiab nws chav tsev yog m2 / m3. Qhov loj dua qhov tshwj xeeb cheeb tsam thaj chaw ntawm kev ntim khoom, qhov loj dua qhov roj-kua hloov chaw loj tau muab. Yog li no, tshwj xeeb thaj tsam thaj chaw yog qhov ntsuas tseem ceeb los ntsuas qhov ua tiav ntawm tus muab tub lim.
(2) Porosity Qhov khoob khoob ntawm qhov ntim ntawm qhov ntim ntawm qhov muab tub lim yog hu ua porosity, qhia hauv e, thiab nws qhov ntsuas yog m3 / m3, lossis qhia hauv%. Ntau qhov porosity ntawm qhov muab tub lim, qhov ntau dua cov roj kis tau thiab qhov qis ntawm txoj haujlwm siab. Yog li ntawd, porosity yog lwm qhov taw qhia tseem ceeb rau kev ntsuam xyuas kev ua haujlwm ntawm cov tub lim.
(3) Filler factor Qhov feem ntawm qhov tshwj xeeb saum npoo ntawm qhov muab tub lim mus rau qhov cub qhov cub, uas yog a / e 3, yog hu ua tus muab tub lim, qhia ua f, thiab nws chav tsev yog 1 / m. Nws sawv cev rau lub zog hydrodynamic ntawm qhov muab tub lim, tus me f tus nqi, qhov tsawg dua qhov ntws tsis kam.
Qhov ua tau zoo ntawm tus muab tub lim tsuas yog nyob ntawm:
Qhov loj me dua thaj tsam thaj chaw (m2 / m3 ntim txheej)
Cov kua muaj cov teeb meem zoo nkauj faib rau saum npoo ntawm qhov muab tub lim
Cov huab cua ntws tuaj yeem faib tusyees hauv txheej txheej
Tus muab tub lim muaj qhov khoob loj heev (m3 / m3 txheej muab tub lim).
Nyob hauv tib qho kev ua haujlwm, qhov loj dua qhov tshwj xeeb cheeb tsam ntawm qhov muab tub lim, ntau cov khaub ncaws tsis zoo ntawm cov roj-kua faib, thiab qhov zoo dua qhov chaw ntub dej, qhov ntau dua huab hwm coj hloov chaw ua haujlwm; qhov ntau dua qhov porosity ntawm qhov muab tub lim, qhib ntau cov qauv, qhov ntau ntawm cov flux Qhov ntau ntawm qhov poob siab, qis qis dua. Kev siv cov fuzzy kev ua lej los ntsuas qhov ua tau zoo ntawm cuaj qhov kev txau siv, qhov kev ua tiav ntawm cov hlau tsis xeb corrugated pob yog qhov zoo tshaj plaws, thiab Raschig nplhaib yog qhov phem tshaj plaws.
Qhov kev xaiv ntawm kev ntim tawm nrog txiav txim siab txog hom, qhov tshwj xeeb thiab cov khoom ntawm pob. Qhov muab tub lim yuav tsum tsis tsuas yog ua tiav cov kev xav tau ntawm cov txheej txheem ntau lawm, tabsis tseem yuav txo qis cov cuab yeej siv nqis peev thiab cov nqi khiav lag luam.
