Analogy between momentum and heat transfer in liquid–solid fluidized beds

• Fluid–particle interphase drag coefficient in liquid–solid fluidized beds
• Wall-to-bed heat and mass transfer in particulate fluidized beds of spherical particles
• Analogy between momentum, heat and mass transfer in particulate fluidized beds

Wall-to-bed heat transfer in particulate fluidized beds of spherical particles was studied. Experiments were performed using spherical glass particles of 0.80–2.98 mm in diameter with water in a 25.4 mm I.D. copper tube equipped with a steam jacket.Heat transfer data related to the fluid–particle interphase drag coefficient were obtained and compared with previous results for wall-to-bed mass transfer in fluidized beds [Bošković et al., Powder Technol., 79 (1994) 217].All the data for momentum, heat and mass transfer in particulate fluidized beds of spherical particles, showed the existence of an analogy among these three phenomena.
