摘要
Characteristic gas-thermodynamic parameters of interaction of mono- and polydisperse jets with solids under pressures p (0) up to 2 MPa and at stagnation temperatures T (0) = 288-1750 K are investigated. The dependence of the velocity of collision of particles with the flowed solid on their material, size, and initial mass fraction in a settling chamber is taken into account. The regions of absolutely inelastic (erosion) and elastic (with a rebound) interactions of particles with the solid is studied. The semiempirical coefficient providing agreement between the theoretical and experimental densities of the heat flow, brought by particles to the solid in the mode of erosion interaction, is found for the case of a hot jet.
