The fluidisation characteristics of particles which are of such a size and density that the velocity of gas in the dense phase exceeds the rising velocity of the bubbles have been studied.Spherical particles in the range 1–2 mm were fluidised in two- and three-dimensional equipment. Minimum ...
[29] compared the difference in air particles between MV and IJV, indicating that the IJV has high efficiency in removing pollutants. For mixed ventilation, the location of the pollutant source has a negligible effect on the diffusion of pollutants in the respiratory zone [30]. The concept of...
The dimensions of the reactor are set considering the optimal velocity of fluidization and the entrainment of particles; - In the second part, the dimensions of the reactor and the optimal velocities are double checked using the Grace diagram to calculate the fluidization regime and checking that ...
