Hauv cov dej ntws, muaj ob daim ntawv, laminar flow thiab turbulent flow. Hauv kev tsim qauv thiab siv lub taub hau, peb feem ntau siv laminar ntws lossis ntws ntws kom ua tiav cov haujlwm tshwj xeeb.

Txog kev tsim lub taub hau, feem ntau peb xav kom tau txais laminar dav hlau cuam tshuam. Laminar ntws txhais tau tias lub dav hlau zoo tuaj yeem tswj tau thiab tus nqi ntws tau ruaj khov, uas yog qhov tseem ceeb rau ntau lub taub hau. Cov kua ntws hauv cov yeeb nkab feem ntau ntws tsis txaus. Xeev, qhov no yog tshwm sim los ntawm sab hauv phab ntsa ntawm cov raj xa dej tsis zoo txaus, lossis muaj ntau qhov sib txuas ntawm cov yeeb nkab, qhov tsis tuaj yeem tswj tsis tau yog feem ntau tsim ntawm cov yeeb nkab sib txuas, uas cuam tshuam nrog cov tshuaj tsuag ib txwm ntawm lub taub hau thiab cuam tshuam cov tshuaj tsuag.

Kev daws teeb meem yog kom cia cov kua hla los ntawm cov yeeb nkab ncaj thiab ntev ua ntej nws ntws mus rau lub qhov taub, uas tuaj yeem txo qis kev tsim kev kub ntxhov, tab sis qhov no yuav ua rau qhov chaw teeb tsa ntawm lub taub hau nyob deb ntawm cov kab yeeb nkab tseem ceeb, ua rau cov tshuaj tsuag kom siv ntau Qhov Chaw, thiab tseem nrog lwm yam teeb meem.

Tom qab tshawb fawb ntev txog qhov no, peb tau tsim cov cuab yeej xws li lub tshuab tso dej kom ruaj khov.Nws muaj ob peb txoj kab ncaj nraim sab hauv.Thaum cov kua nkag mus rau qhov dej khov ruaj khov, vim qhov thaiv ntawm phab ntsa ntawm txhua cov channel, tiam ntawm kev kub ntxhov yog txo qis.

Cov tshuaj ruaj khov uas peb tsim thiab tsim muaj ntau yam duab thiab qhov ntau thiab tsawg, koj tuaj yeem tiv tauj peb txhua lub sijhawm kom tau txais cov ntaub ntawv ntau ntxiv ntawm cov khoom lag luam lossis cov khoom lag luam qis tshaj.
