The segregation behavior of a mixture of silica-coated titanium dioxide(TiO2)particles of three different sizes in a pseudo two-dimensional fluidized bed was studied experimentally by the freeze-sieving method and numerically by the multi-fluid model(MFM).Three-dimensional computational fluid dynamics(CFD)simulations were carried out to evaluate the effects of the solid wall boundary conditions on particle segregation in terms of specularity and particle-wall restitution *** quantitative indexes of segregation tendency and segregation degree were used to determine the axial segregation of the mixture in triangular *** simulation results revealed that the axial segregation increased with the specularity coefficient,whereas the particle-wall restitution coefficient had a minor effect on axial *** of the simulation results with experimental data showed that the appropriate value of the specularity coefficient used in the CFD model depended on superficial gas *** study of the effects of superficial gas velocity on segregation behavior demonstrated that the greatest segregation was obtained at minimum fluidization velocity and the segregation decreased as the gas velocity gradually increased.

＜正＞ In this paper, the cycle performance experiments of an air conditioner under different composition ternary mixtures based on R407c were carried out with the air enthalpy difference method facility. The research was done about capacity decreasing experiments under different conditions. The relationship that the cooling capacity is decreasing with the Rl34a composition increasing was obtained. It is shown that the cooling capacity can be adjusted with the varying composition of the ternary refrigerant mixture.
