Experimental study of a liquid fluidization in a microfluidic channel

Lookup NU author(s): Dr Vladimir Zivkovic



This study reports the first ever experimental study of true micro-fluidization: a liquid-fluidized bed of 30.5 μm micro-particles within a rectangular micro-channel of 400 × 175 μm2. The failure to fluidize the micro-particles with water demonstrated the importance of surface forces for micro-fluidization. Use of ethanol instead leads to fluidization that is largely well described by conventional fluidization equations, although higher values of empirical constant (k and n) are obtained for Richardson-Zaki correlation.
