폴리스틸렌 입자로 된 서스펜션의 침강속도에 관한 연구 = A Study on the Settling rate of Suspensions of Polystyrene particles

다국어 초록 (Multilingual Abstract)

An experimental study was carried out to investigate the settling rate of polystyrene particles of different sizes in monodisperse suspensions and the effect of volume concentration and size distribution on the settling rate in binary suspensions.
As a results, the slope index n (the slopes obtained from the line of logarithm of settling rate versus logarithm of voidage) increased with the particle size decreasing, which were different from Richardson-zaki experiment results.
The curves of log u_c versus log ε changed radically in slope between ε (voidage)=0.9 and ε=1, as shown in the result of the experiment of Davies et al.
The critical volume concentretion of particles for the interlocking of two neighboring setting interfaces in binary suspensions depended not only on the ratio of particle sizes but also on the ratio of volume concentration of particles.
