Heat Transfer between Immersed Surfaces and Gas-Fluidized Beds
TL;DR: In this article, the available experimental and theoretical information concerning the bed-to-surface heat-transfer coefficient is discussed, along with the design of the gas distributor plate and the relative size of heat transfer surface and the fluidized bed.

Heat Transfer to Small Horizontal Cylinders Immersed in a Fluidized Bed
TL;DR: In this paper, the authors used resistively heated cylindrical samples ranging from 1.3 to 9.5 mm in diameter at fluidizing rates ranging from approximately 0.5 x G{sub mf} (packed bed condition) to over 10 times G{ sub mf] using aluminum oxide sand particles ranging from d{sub p}=145-330 {mu}m (50-90 grit).

Solids motion caused by a bubble in a fluidized bed
B. Singh,C. Fryer,Owen E. Potter +2 more
TL;DR: In this article, the authors examined the effect of the wake on the interpretation of displacement profiles using a thin layer of tracer particles and showed that the wake area is 13-28% of the bubble area.
