Key words and phrases: drying; fluidized bed; moisture measurement; nu-clear-magnetic-resonance; population balance.
Abstract: Drying in fluidized beds is of great practical significance because of good performance, low investment and maintenance costs and robustness of the respec-tive equipment. Traditional modeling approaches for continuous dryers consider the disperse solids as a phase with average properties such as particle size, moisture content and enthalpy. To gain a better understanding of the interaction between process condi-tions, material properties and product quality the traditional drying models basing on averages need to be extended to describe the effect of distributed material properties. For this extension the concept of population balances provides the adequate framework. In this paper the simplest possible analytical solution for particle moisture distribution in a continuous, well mixed fluidized bed dryer is presented. These solutions enable to easily investigate and discuss the influence of parameters like single-particle drying curve and particle flow rate (residence time) on the distribution of residual moisture in the product. Additionally a new technique is presented to measure the moisture distribu-tions of the dried solids. The experimental results are compared with the population balance model.

Key words and phrases: finite rotations; first-order plate theory; large rigid-body motion.
Abstract: A first-order seven-parameter theory of plates undergoing finite rota-tions is developed. The precise representation of large rigid-body motions in the dis-placement patterns of the plate elements is considered. The fundamental unknowns con-sist of six in-plane and transverse displacements of the face planes and an additional transverse displacement of the midplane. Because of thickness stretching the 3D equa-tions of Hooke's law are utilized. However, no thickness locking can be observed in the proposed plate model. This is demonstrated by analytical and numerical studies of the isotropic plate bending.
