Computational fluid dynamics (CFD) is a branch of fluid mechanics uas siv cov zauv txheeb xyuas thiab cov ntaub ntawv cov qauv los tshuaj xyuas thiab daws cov teeb meem uas cuam tshuam nrog cov dej ntws.
Yuav ua li cas xam cov kua dej dynamics siv tau rau?
Computation fluid dynamics (CFD) is an engineering tool used to simulate the action of thermo-kluids in a system. Nws yog siv los ntawm ntau qhov kev lag luam hauv lawv txoj haujlwm txhim kho los tshuaj xyuas, ua kom zoo dua qub thiab txheeb xyuas qhov ua tau zoo ntawm cov qauv tsim ua ntej tus qauv tsim thiab kev sim lub cev.
Dab tsi yog qhov teeb meem ntawm kev suav cov kua dej dynamics qauv?
Qhov tsis zoo ntawm kev sim virtual nrog CFD:
yuam kev tuaj yeem tshwm sim vim cov qauv ntws yooj yim lossis yooj yim ciam teb . muaj peev xwm tsis paub tseeb tshwm sim los ntawm kev suav me me dhau lawmib lub xovtooj thiab yog li ua rau cuam tshuam kev cuam tshuam. Kev suav sijhawm yuav txuas ntxiv rau cov qauv loj.
Puas suav cov dej dynamics ua haujlwm zoo?
Yog tias koj nkag mus rau hauv tshuab lossis aerospace engineering nrog kev txaus siab rau cov dej dynamics, CFD yog qhov tsis txaus ntseeg fruitful txoj haujlwm xaiv rau koj mus nrhiav.
CFD nyuaj npaum li cas?
CFD, raws li qhov yooj yim nws yuav zoo li, yog qhov nyuaj hauv kev xyaum. Raws li qib siab intricate lej thiab physics. CFD siv Navier-Stokes sib npaug los kwv yees qhov ntws ntawm cov kua lossis roj.

Thaum qhov sib npaug ntawm ob lub kua sib xyaw?
Thaum qhov sib npaug ntawm ob cov kua sib xyaw, qhov qhov tshwj xeeb ntawm qhov sib tov yog 4. Thaum cov khoom sib npaug ntawm tib ob cov kua sib xyaw ua ke qhov tshwj xeeb lub ntiajteb txawj nqus ntawm qhov sib tov yog 3. Thaum qhov sib npaug ntawm ob cov kua sib xyaw ua ke qhov tshwj xeeb lub ntiajteb txawj nqus?
Puas yog cov kua dej nres lub hwj chim tswj cov kua dej?
Cov kua nplaum thiab lub hwj chim tswj cov kua dej yogob lub kua siv hauv lub tshuab hydraulic hauv cov tsheb niaj hnub, tab sis qhov zoo sib xws tsis mus deb tshaj qhov ntawd. Nres thiab lub hwj chim tswj cov kua dej tau tsim thiab ua kom zoo nyob rau ntau xyoo los ua haujlwm sib txawv hauv cov tsheb, thiab lawv tsis hloov pauv.
Puas yog cov roj cholesterol ua kom cov kua dej ua kua dej?
Thaum qhov kub thiab txias, cov roj cholesterol ua rau cov kua dej ua kom cov kua dej ntau dualos ntawm kev tiv thaiv cov lipids los ntawm kev ntim khoom sib ze. Thaum qhov kub thiab txias, cov roj (cholesterol) yuav txo qis hauv daim nyias nyias.
Puas yog kev sib tw tsis sib xws tib yam li kev sib xyaw ua ke?
Kev txwv tsis pub sib tw yog qee zaum xav tias yog tshwj xeeb ntawm kev sib xyaw inhibition. Hauv kev sib xyaw inhibition, tus inhibitor khi rau ib qho chaw allosteric, piv txwv li ib qhov chaw sib txawv ntawm qhov chaw nquag uas lub substrate khi.
Puas cov sib tov sib xyaw ua ke muaj cov khoom sib xws?
Ib homogeneous sib tov yog sib tov nyob rau hauv uas muaj pes tsawg leeg yog uniform thoob plaws qhov sib tov .. Qee cov ntaub ntawv hais ntxiv tias cov tshuaj lom neeg tsis tuaj yeem muab cais rau hauv nws cov ntsiab lus los ntawm kev sib cais ntawm lub cev, piv txwv li, tsis muaj kev cuam tshuam tshuaj lom neeg.
