- •
Gas holdup in two and three phase fluidized bed has been measured experimentally.
- •
Mass and heat transfer coefficients were evaluated at different solid contents.
- •
Cooling and humidification of air bubbles into a water-sand slurry was the model.
- •
At solid contents 30% the transfer coefficients increased by a factor ranged from 2 to 5.
- •
Gas velocity becomes ineffective on the transfer coefficients at high solid contents.
