| Abstract: | In previous reports we have outlined the equations governing the flow of a mixture of a fluid infused with solid particles, the equations governing the state of uniform fluidization and the equation governing the linearized stability of the state of uniform fluidization. We have also discussed how material function β₀₁, the pressure like term, i.e., the spherical part of the stress tensor for the solid constituent, could play a stabilizing role. We have carried out the optimization study for the stability equations and have obtained bounds for this material function β₀₁, which will ensure the stability of the state of uniform fluidization for a range of values for the other material parameters. Here, we provide few preliminary results which show the effect of different material parameters on the stability of the state of uniform fluidization. Figures (1) through (10) show the variation of the root of the characteristic equation with the wave number, σ. Negative values for the root implies that the flow is stabe and positive values that the flow is unstable. For the sake of completeness, we provide the section on stability which can also be found in our previous report. |
