ON HEAT OR MASS TRANSFER BETWEEN THE FLUIDIZING AGENT AND THE SOLID PARTICLES OF THE FLUIDIZED BED (in Rumanian)
BS>The problem of heat or mass transfer between the fluidizing agent and the solid particles is examined, both in the case of homogeneous fluidization and in that of nonhomogeneous fluidization. In the first case the experimental results are correlated, by using,the following equations Nu =0.426 Re/sup 0.30/ Ar/sup 0.17/ Pr/sup 1/3/ for Re Ar/sup -0.40/ <2.15 and Nu = 0.943 Re/sup -1/ Ar/ sup 0.69/ Pr/sup 1/3/ for Re Ar/sup -0.40/> 2.15, where Nu, Re, Ar, and Pr are Nusselt's, Reynolds', Archimedes', and Prandtl' s numbers. Nu, Re, and Ar numbers are computed with the diameter of the particle. In the second case, of non-homogeneous fluidization, the problem of the adequate definition of the transfer coefficient is discussed and the reason why small values are obtained for the transfer coefficients, such as they are defined in the literature, is explained.
