Heat transfer on tube bundles embedded horizontally in a liquid-fluidized bed was investigated experimentally. In the experiment, a total of 5 kinds of tube bundles in an equilateral triangular staggered arrangement, including a single tube, was used. Tested particles were of glass and ceramics, and
Measurements of the bubble hydrodynamics were carried out in a cold pressurized bed with horizontal tubes. The mean bubble rise velocity, the bubble frequency, the mean pierced length, the bubble volume fraction, and the visible bubble flow rate were measured using capacitance probes. The absolute g
## Abstract Heat transfer coefficients were measured on tube bundles of fundamental layouts including inβline layouts embedded horizontally in a liquidβfluidized bed. Tested tube layouts were single tubes, transverse single tube rows, longitudinal single tube rows, and inβline arranged tube bundles
## Measurements of the visible bubble flow rate and the through-flow velocity of gas inside bubbles were made in a pressurized fluid&d bed, using capacitance and Pitot-static pressure probes, respectively. The influence of pressure and fluidiition velocity on the bubble behaviour and gas Row distr
