摘要
Abstract
In order to study the aerosol particle penetration through surrogates of cracks in building envelopes, the simulating experiments were done in laboratory.The particle size and velocity of flow and crack height were the three main factors that governed fractional particle penetration.The particle penetration increased for higher velocity of flow,and with height of crack grows the penetration increased too.The supermicron and ultrafine particles were significantly removed by means of gravitational settling and Brownian diffusion, respectively.The particles in size about 0.5 μm had the highest penetration.关键词
