Cov txheej txheem kub hloov mus rau hauv cov txheej txheem ceramic fiber ntau yog qhov nyuaj heev. Vim lub siab porosity ntawm cov khoom nws tus kheej, cov ceramic fiber module muaj cov yam ntxwv ntawm thermal conductivity thiab tsis tshua muaj cua sov cia. Lub thermal conductivity ntawm huab cua thiab feem ntau gases yog tsawg heev, uas kuj cov yam ntxwv ntawm cov ntxeem tau refractory fibers yog txiav txim. Ib zaug nyob rau hauv lub cub tawg rau lub hom phiaj tshwj xeeb, cov huab cua xws li txo cov cuab yeej ntawm lub cub tawg roj hloov zoo heev, thiab thermal conductivity ntawm refractory ceramic fibers kuj yuav hloov.
Ceramic fiber module rauv phab ntsa yog perpendicular mus rau sab hauv ntawm qhov kub thiab txias nto. Cov txheej txheem hloov hluav taws xob feem ntau yog nyob ntawm convection thiab hluav taws xob. Raws li qhov kev ncua deb ntawm lub puab nto nce thiab qhov kub ntawm qhov sib txawv maj mam txo, lub convection thiab hluav taws xob raug thaiv, thiab lub zog kuj yog attenuated. Nyob rau lub sijhawm no, cov cua kub hloov mus rau hauv cov phab ntsa ntawm lub cub tawg feem ntau yog raws li kev coj ua. Rau cov phab ntsa ntawm lub cub tawg uas yog qhov tseem ceeb tshaj plaws, yog tias qhov porosity loj, cov nyhuv thermal rwb thaiv tsev yog qhov zoo tshaj plaws. Yog li ntawd, lub thickness ntawm lub cub tawg phab ntsa, kev xaiv ntawm cov composite txheej thiab cov khoom ntawm txhua txheej yuav tsum tau ua ntej raws li qhov kub ntawm lub cub tawg. Rau cov nyhuv rwb thaiv tsev ntawm lub qhov cub, thermal rwb thaiv tsev yog qhov tseem ceeb heev.
Adiabatic yog qhov siab tshaj plaws tiv thaiv kev hloov pauv ntawm cov cua sov, uas yog, cov khoom siv thermal rwb thaiv tsev yuav tsum muaj cov thermal conductivity me me, kev hloov hluav taws xob hloov hluav taws xob thiab hluav taws xob hloov hluav taws xob coefficient, uas yog, cov khoom siv no yuav tsum muaj kev ua haujlwm siab thermal. Qhov no yog txiav txim los ntawm cov nram qab no yam:
1) Cov qauv ntawm cov khoom siv;
2) Pom pom qhov ntom ntom;
3) Qhov loj thiab cov yam ntxwv ntawm qhov pores;
4) Cov av noo;
5) Thaum tshav kub kub kev taw qhia;
6) Kub thiab lwm yam.
