Lub plhaub thiab lub raj xa hluav taws xob muaj cov khoom siv xws li lub plhaub, lub raj xa hluav taws xob, lub raj phaj, baffle phaj (baffle), thiab lub thawv raj.Lub plhaub feem ntau yog cylindrical, nrog ib pob ntawm cov kav dej ntsia tau rau hauv, thiab ob qhov kawg ntawm lub pob yog tsau rau ntawm lub raj phaj.Muaj ob hom kua rau kev sib hloov cua sov: txias thiab kub.Ib qho ntws hauv lub raj thiab hu ua lub raj sab dej;Lwm hom ntws tawm sab nraum lub raj yog hu ua plhaub sab kua.Txhawm rau txhim kho cov cua sov coefficient ntawm cov kua dej sab nraud ntawm cov yeeb nkab, ob peb baffles feem ntau yog ntsia hauv lub plhaub.Baffles tuaj yeem ua kom cov kua dej nrawm nrawm ntawm lub plhaub sab, yuam cov kua dej hla lub raj ntim ntau zaus raws li txoj hauv kev tau teev tseg, thiab txhim kho cov qib ntawm cov kua dej turbulence.Cov raj cua sov tuaj yeem muab tso rau hauv cov duab peb sab sib npaug lossis cov squares ntawm lub phaj phaj.Qhov sib npaug ntawm daim duab peb sab yog qhov sib npaug, nrog rau qhov siab ntawm qhov kub thiab txias ntawm cov kua dej sab nraud ntawm cov yeeb nkab thiab cov coefficient ntawm cov cua kub loj;Ib qho kev npaj square ua rau kev tu sab nraud ntawm cov yeeb nkab yooj yim thiab haum rau cov kua dej uas ua rau cov scaling.
