Peb-dimensional tov khoom yog siv cov neeg kho tshuab quab yuam thiab lub ntiajteb txawj nqus, ob los yog ntau hom ntawm cov ntaub ntawv sib tov sib xyaw tshuab, sib tov machinery yog dav siv nyob rau hauv tag nrho cov hom ntawm kev lag luam thiab lub neej txhua hnub, nws yuav ua tau ntau yam ntaub ntawv nrog ib tug sib tov sib xyaw, xws li cement, xuab zeb, gravel thiab dej sib tov rau hauv cov khoom ntub dej; Nws tseem tuaj yeem ua rau thaj chaw sib cuag ntawm cov khoom siv los txhawb cov tshuaj lom neeg; Nws tseem tuaj yeem ua kom lub cev hloov pauv, xws li ntxiv cov granular solutes rau cov kuab tshuaj, uas tuaj yeem ua kom nrawm nrawm thiab sib tov los ntawm lub luag haujlwm ntawm kev sib xyaw tshuab. Feem ntau siv peb-dimensional mixers yog muab faib ua plaub pawg: roj thiab viscosity tsawg viscosity kua mixers, nruab nrab thiab siab viscosity yoj lub cev thiab slurry mixing machinery, thermoplastic khoom tov khoom, hmoov thiab granular khoom sib tov machinery.
Kev sib xyaw ua kua hauv 3D tov khoom
Kev sib tov xav kom tag nrho cov ntaub ntawv koom nrog hauv kev sib xyaw yog sib npaug sib npaug, thiab cov qib ntawm kev sib xyaw yog muab faib ua qhov zoo tagnrho sib xyaw, random sib xyaw thiab "tsis muaj kev sib xyaw" peb lub xeev, qhov kev sib xyaw ntawm ntau yam khoom siv hauv cov tshuab sib xyaw yog nyob ntawm qhov kev faib ua feem. cov ntaub ntawv yuav tsum tau tov, lub cev lub cev thiab cov yam ntxwv, raws li zoo raws li hom kev sib tov machinery siv thiab lub sij hawm ntawm kev sib tov ua hauj lwm thiab lwm yam.
Kev sib xyaw ntawm cov kua dej feem ntau yog nyob ntawm tus neeg kho tshuab stirrer, cov cua ntws thiab lub dav hlau ntawm cov kua yuav tsum tau soaked, kom cov khoom yuav tsum tau agitated kom ua tau zoo sib xyaw. Kev ntxhov siab ua rau ib feem ntawm lub cev nthwv dej ntws, thiab cov kua ntws ntws thawb cov kua nyob ib puag ncig nws, ua rau tsim cov kua dej ntws hauv cov yaj, qhov tshwm sim ntawm cov kua qhov chaw hu ua lub ntsiab convection diffusion, thaum cov kua. ntws los ntawm agitation; Thaum qhov ceev ceev heev, shear txiav txim siab tshwm sim ntawm qhov sib cuam tshuam ntawm cov kua dej ceev ceev thiab cov kua dej uas nyob ib puag ncig qis qis, ua rau muaj coob tus hauv zos vortices, uas sai sai kis mus rau plaub sab, thiab cov kua ntau dua. koom nrog hauv vortex hauv ib qho me me ntawm kev tsim ntawm chaotic convection diffusion hu ua eddy diffusion.
Cov khoom txav ntawm cov neeg kho tshuab agitator kuj muaj qhov cuam tshuam rau lub cev yoj thaum tig, thiab lub cev yoj kuj raug cuam tshuam los ntawm kev cuam tshuam thaum ntws los ntawm phab ntsa ntawm lub cuab yeej thiab ntau yam khoom ruaj ruaj tau nruab rau hauv lub thawv, uas yuav ua rau ntau heev. ntawm lub zos vortex diffusion
Lub ntsiab lub cev convective diffusion thiab eddy diffusion tshwm sim los ntawm nplawm nce qhov chaw ntawm molecular diffusion ntawm txawv kev kawm thiab txo qhov diffusion nrug, yog li shortening lub sij hawm molecular diffusion. Yog hais tias lub viscosity ntawm cov kua yuav tsum tov tsis siab, nws muaj peev xwm ncav cuag lub random mixing xeev nyob rau hauv ib tug luv luv stirring lub sij hawm. Yog tias qhov viscosity siab dua, lub sijhawm sib xyaw yog ntev dua.
Rau cov kua uas sib txawv, muaj pes tsawg leeg thiab insoluble, shear nkaus thiab muaj zog turbulence tsim los ntawm nplawm yuav rhuav lub ntom yoj lub cev mus rau hauv me me tee dej thiab disperse lawv tusyees mus rau hauv lub ntsiab yoj lub cev, thiab cov kua ntws ceev generated los ntawm stirring yuav tsum ntau dua. txoj kev ceev ntawm lub yoj droplet.
Thaum lub sij hawm ua hauj lwm ntawm peb-dimensional tov khoom, vim hais tias nyob rau hauv ntau txoj kev khiav hauj lwm ntawm lub mixing chim, qhov ntws thiab diffusion ntawm ntau yam ntaub ntawv yog ceev thaum lub sij hawm sib tov, thiab lub ntiajteb txawj nqus segregation thiab tsub zuj zuj ntawm cov ntaub ntawv los ntawm lub centrifugal quab yuam. ntawm cov khoom siv dav dav raug zam, uas tuaj yeem ua kom zoo dua ntawm cov khoom sib xyaw.
