Equations of motion based on the theory of interacting and interpenetrating continua are used to study pattern forming instabilities in two-dimensional dispersed two-phase flows such as a suspension of particles in a fluidized bed and a bubbly gas-liquid flow. By making use of analytical and numerical bifurcation techniques it is shown that the main instability sequence in a vertically suspended configuration consists of the transition from a homogeneous flow through a one-dimensional concentration wave train to a two-dimensional traveling wave.
