Tus ua hauj lwm ua haujlwm ntawm nruab nrab-efficiticy huab cua lim tsuas yog suav nrog kev cuam tshuam, inertia thiab diffusion, electrostatic, electrostatic, electrostatic, thiab lwm yam. Tshwj xeeb:
Kev cuam tshuam: thaum plua plav tawm hauv cov huab cua txav nrog lub airflow, thaum lawv ntaus cov khoom xws li cov khoom, lub van der waals yuam ntawm cov khoom ua rau cov khoom tawg rau cov khoom muaj fiber ntau.
Inertia thiab diffusion: hais ntawm plua plav txav inertially nyob rau hauv lub airflow. Thaum lawv ntsib cov fibers, lub Airflow hloov kev taw qhia. Cov me nyuam cuam tshuam los ntawm cov kev taw qhia thiab ntaus cov fibers thiab raug sib khi vim yog inertia; Cov khoom siv me me ntawm cov plua plav ua cov lus tsa suab xim av tsis xwm yeem, muaj ntau txoj kev ntaus cov teeb meem, thiab tseem tuaj yeem lim.
Cov nyhuv electrostatic: fibers thiab hais thiab cov khoom siv yuav ua cov tshuab hluav taws xob kom hloov nws txoj hnyuv thiab ntaus pob thiab sib luag dua. Cov hluav taws xob zoo li qub ua lub luag haujlwm ntawm lub luag haujlwm hauv lub zog ua haujlwm.
