Heat Transfer in Fluidized Beds, 1997 Particle Technology Series, Vol. 11

This book provides a much needed and thorough treatment of the heat transfer in agitated disperse systems. It gives predictive equations for the heat transfer in moving beds, bubbling and circulating fluidized beds, pneumatic transport in vertical tubes and particulate fluidized beds. Owing to the many different modes of activation of heat transfer, the basic approach of the book is to provide experimental evidence of the relevance of particle motion to the proximity of solid surfaces for the heat transfer observed. This has been achieved by the evaluation of experiments obtained with a newly developed pulsed light method using luminous particles. Heat Transfer in Fluidized Beds will be of great use to students and researchers involved in heat transfer and thermodynamics.
