Abstract: Literature relating to improvement of fluidization performance in case of gas-solid systems by the incorporation of baffles in columnar beds and use of conical conduits has been briefly reviewed. Investigations relating to gas-solid fluidization have been carried out in four different types of conduits, viz, cylindrical, baffled cylindrical with VT baffles, baffled cylindrical with ST baffles and conical. From a dimensional analysis approach, correlations have been proposed for the prediction of fluctuation ratio in terms of static and dynamic characteristics of the system for the conventional and the modified conduits. The quality of fluidization, measured in the scale of fluctuation ratio, has been compared for the above cases and the quantitative improvement achieved in case of the modified conduits over the conventional one has been presented.
