Abstract

In article are considered a status of layers for the systems "solid body-solid body" in case of liquefaction in the liquid environment when superimposing a gas flow and also critical speeds of a three-phase fluidized layer. The experimental data on the speed of the beginning of pseudo-liquefaction of Reps and ablation of Reab of bodies of irregular shape are generalized in the form of criteria formulas. Results on critical speeds slightly differ from the received estimated formulas. The received formulas describe boundaries of transition of statuses of a layer in a broad range of change of the equivalent diameter of particles of irregular shape. Advantages of three-phase pseudo-liquefaction to the above-named bodies of irregular shape are also given.
