DETERMINATION OF HEAT AND MASS TRANSFER EFFICIENCY ON A BUBBLING PLATE WITH ACCOUNT FOR SCALE TRANSITION

The effi ciency of heat and mass transfer in the bubbling bed on the plate has been investigated with the use of the method of combined physical and mathematical modeling based on the representation of the physical process in the form of a combination of elementary phenomena having a hierarchy of scales that permits realizing a scale transition in designing a contact device. The mathematical modeling of the heat and mass transfer in the above bed is based on the idea that the structure of this bed is invariant with its size and the interaction of the phases in it. A parametric investigation of the interaction of various effects in the process of heat and mass transfer in the bubbling bed on the plate and their conjugation has been carried out on the basis of the variational formulation of the conservation laws. Examples of calculating the effi ciencies of the heat and mass transfer processes on bubbling plates are given. The results of calculations were compared with the corresponding experimental data.
