Heat transfer coefficients at a pipe coil submerged to the fluidized bed

The paper brings the summary of series of measuurements of heat transfer from water to quarz sana - air fluidized systems through the wall of pipe coil probe. A computational algorithm is developed to calculate the heat transfer coefficient at the fluidized bed side of the coil. The results are presented in nondimensional forms for the vicinity of optimum fluidization velocity working points of the bed. The obtanied results are in fair accordance with findings of the authors.
