Abstract

Experimental results for instantaneous and time-averaged local heat transfer coefficients, as well as local voidage and pressure are used to validate the Adams-Welty analytical model of heat transfer to a horizontal cylinder in large-particle fluidized beds. Results support the main assumptions of the model and show that the range of applicability is wider than originally expected.
