Research Interests

RESEARCH FOCUS (2003-2012)

  • Hydrodynamics of Liquid-Fluidized Beds (a technique for mobilizing and contacting solid particles by an upward or downward flow of liquid)
  • Dynamics of Spouted Beds (a technique for mobilizing and contacting coarse solid particles by means of an upwardly directed gas jet located at the bottom of the bed of solids)
  • Fouling of heat exchangers
