John Davidson

Professor John Davidson FREng FRS


Elected: 1974


John Davidson has successfully applied science to a number of problems in chemical engineering. His work has included the study of thin liquid films and accompanying mass-transfer in packed columns, and also various aspects of the mechanics of single bubbles and swarms of bubbles. However, his principal contributions over the last ten years have been in the industrially important field of fluidisation. John’s work, theoretical and experimental, has thrown much light on the mechanics of fluidised beds and has simplified the study of a variety of particulate systems. It has also made possible the analysis of chemically-reacting fluidised systems.
