This paper studies the fluid-dynamic behaviour of a fluidization gas distributor in the absence of particles. This work is divided into two complementary parts: a numeric simulation of the flow field generated by the distributor using a three-dimensional model and experimental measurements of velocity with a hot wire anemometer in a real scale model to validate the numerical results. The parametric...
It is shown that the two-phase model for bubbling gas-solid fluidized beds can be extended to bubble column slurry reactors operating in the heterogeneous flow regime by proper definition of the 'dilute' and 'dense' phases. The 'dilute' phase in a bubble column slurry reactor is to be identified with the fast-rising 'large' bubbles. The 'dense' phase consists of the slurry phase in which 'small'...
