1.} sib xyaw ua ke
Lub tshuab: Sib xyaw npab ncaj qha tsav lub zog thiab kev sib tsoo ntawm caj npab ua kom muaj kev sib cuam tshuam, txo homogeneity thiab txhim kho homogeneity.
Ua rau:
Tsawg dua caj npab: Tsim cov great loj dua, ua rau cov khoom sib faib khoom tsis sib xws (e {}}}}}}}} Cov txheej txheem hauv cov pob zeb lossis pastes) {2}.
Ntau Caj Npab: Tsim kom muaj cov qauv me me, ua kom muaj kev sib xyaw ua ke, txhim kho caj ces, hauv cov txiv caj npab tuaj yeem tsoo cov nplais thiab cov khoom lag luam ntxiv rau kev sib txawv.
Kev Kawm Txog: Cov kev tshawb fawb qhia tau hais tias nce cov hmoov caj npab los ntawm 4 mus rau 8 hauv kev txhim kho cov khoom sib xyaw los ntawm 25% rau cov ntaub ntawv viscous {}}
{{0 {}}} sib xyaw sijhawm
Lub tshuab: Tus naj npawb ntawm caj npab cuam tshuam rau covKhoom Siv Tus Nqi. Ntau npab tsim cov pob zeb denser, ua kom nrawm dua kev sib hloov ntawm cov khoom siv rau lub xeev tsis zoo {}}
Ua rau:
Tsawg dua caj npab: Siv sijhawm ntau rau cov sijhawm sib xyaw ua ke vim tias muaj kev sib xyaw ua ke thiab muaj kev ntseeg ntws (e {{}}
Ntau Caj Npab: Lub sijhawm luv luv ua haujlwm los ntawm kev nce thaj tsam ntawm caj npab thiab cov ntaub ntawv ntxiv, txhua tus khub ntxiv ntawm caj npab tuaj yeem txo lub sijhawm sib xyaw los ntawm 8-12%.
Chaw sib pauv-tawm: Caj ces ntau dhau yuav ua rau overmixing (e {{} g}}
3.} kev siv fais fab
Lub tshuab: Tus naj npawb ntawm caj npab cuam tshuam lubluag dagthiabTorque Yuav Tsum Taurau kev ua haujlwm .
Ua rau:
Tsawg dua caj npab: Kev siv hluav taws xob qis vim txo qis kev tawm tsam (e {}}
Ntau Caj Npab: Lub zog xav tau ntau dua vim muaj cov khoom siv tiv taus ntau dua thiab kev sib txhuam tsis tau muaj 20-25% muaj zog dua li ib nrog 4 caj npab hauv qab ntawm tib lub load .
Tsim Kev Txiav Txim Siab: Engineers yuav tsum sib npaug tov nrog lub zog siv hluav taws xob {}} kev hloov kho ntawm cov hluav taws xob tuaj yeem siv ntau lub zog siv .
4.} Cov Khoom Siv Shear thiab Kev Txwv
Lub tshuab: Sib xyaw npab tsim cov rog uas tawg cia agglomerates tab sis kuj tseem tuaj yeem ua rau rhiab cov ntaub ntawv .
Ua rau:
Tsawg dua caj npab: Qis dua shear siv, haum rau cov khoom siv tsis yooj yim (e {{} g}} ... {1 .
Ntau Caj Npab: Hos} Txawm li cas los xij, kev ua kom muaj zog los ua li,
Kev thov kev hloov kho ib qho tshwj xeeb:
Kev lag luam khoom noj: ua ntej tsawg dua caj npab los tiv thaiv kev ntsuas kev ua kom tsis txhob ua rau.
Kev tsim kho: Siv ntau tus caj npab kom ntseeg tau muaj zog shear rau cohesive mixtures .
5.} kub tiam
Lub tshuab: Kev sib txhuam ntawm caj npab, khoom, thiab cov chav ua tov khoom tsim cua hlob cua sov .
Ua rau:
Tsawg dua caj npab: Cov Khoom Siv Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob
Ntau Caj Npab: Cov cua kub siab dua, uas yuav xav tau cua txias rau cov ntawv thov cua sov (e {}} g}!
6. txaus qauv thiab cov chaw tuag
Lub tshuab: Cov kev npaj thiab naj npawb ntawm caj ceg dictate Flow Dynamics (e {}}, axial, radial flow) .
Ua rau:
Tsawg dua caj npab: Tsim cov chaw tuag loj "(thaj chaw nrog cov khoom siv tsawg dua), ua rau tsis tiav tov .
Ntau Caj Npab: Txo cov chaw uas tuag los ntawm kev txhawb nqa multidirefection Flow {{}} Lub caj npab tuaj yeem tshem tawm mus txog 4 caj npab hauv tus txheem tov khoom {}}
