| Abstract: | Within the framework of the simplest one-dimensional model of a fluidized bed as a medium consisting of two interpenetrating interacting fluids, it is shown in the paper that linear thermomechanical oscillations can occur if the gas viscosity depends on the temperature and a nonisothermic chemical reaction takes place in the fluidized bed. The conditions under which oscillations occur and their frequencies are determined and their dependence on the fluidization parameters, the heat loss (or supply) rate, the rate and heat of the reaction, and quantities characterizing the dependence of the gas viscosity on the temperature and the force of the interphase interaction on the concentration of the solid particles is found.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 5, pp. 75–80, September–October, 1984. |
