| Summary: | 碩士 === 國立虎尾科技大學 === 材料科學與綠色能源工程研究所 === 97 === Measurements of the velocity development in the working section is by achieved Laser Doppler Velocimetry (LDV), it is obtained that the turbulence in fully developed.
Sodium salt of fluorescence is produced by TSI 3475 and acts as the measured particles suspended in the air flow of square tube. Aerosol particles deposited on glass plates during 3hr and 5hr, respectively. After the glass plates is soaked in deionized water and measured real value of fluorescence used Hidex Chameleon.
It can therefore be seen that, when the temperature, the velocity and particles diameter are change, the dependent of particles can concentration upon these parameters is obviously observed.
