Abstract |
The successful and economical design, scale up and operation of a fluidized bed reactor depends upon the
true prediction of its bed hydrodynamics. The present research has been carried out to study the hydrodynamics
behavior of bed of semolina particles in liquid solid fluidization. The prime objective of this research work is to study
the effect of liquid superficial velocity and variation in static bed height on the minimum fluidization velocity and
pressure drop. Liquid-solid fluidization is characterized by the uniform expansion of bed particles; therefore, it is
known as particulate fluidization. In liquid, solid fluidization, there is no bubbling phase, that is the main cause of
uniform bed expansion. Liquid-solid fluidization has extensive field of applications, i.e., in hydrometallurgy, waste
water treatment, biochemical processing and food technology. Minimum fluidization velocity and pressure drop are
important hydrodynamic parameters in the design and scale up of fluidized b
