MATHEMATICAL SIMULATION OF THE STRUCTURAL PROPERTIES OF PACKED AND FLUIDIZED BEDS

Based on the algorithm of successive fi lling a given volume with single spheres, a mathematical model of random packing of a limited volume of a bed in the fi eld of body forces has been developed. This model can be applied to electrothermal packed- and fl uidized-bed furnaces and will make it possible to investigate the thermal and electrical conductivity of such beds. A check of the adequacy of the model showed its correspondence to the well-known experimental and calculated results, as well as the stability of the solutions obtained with its aid.
