A bifurcation approach to understanding instabilities in gas-fluidized beds using a single phase compressible flow model

摘要: It has been shown that the equations of motion and continuity for particles in a fluidized bed can be related to those compressible fluid acted upon by density-dependent force. In previous work on flow equations, solution structure fully developed plane (one-dimensional) waves was computed. lose stability lateral direction. this we study two-dimensional solutions which reveal bubble-like evolve both from as well uniform state. A representative value wavenumber is chosen global bifurcation diagram explored, consists number distinct one- branches. The existence mixed mode double humped demonstrated transient simulations are used examine mechanism density wave development coalescence.
