| Abstract: | A mathematical model is constructed and an analytical solution is obtained for the problem of a one-dimensional steady flow
of a mixture of different gases with hollow permeable particles. The case of a one-dimensional unsteady flow of such a mixture
is analyzed numerically. The numerical solutions are compared with experimental data on the motion of the peak concentration
of helium in a fixed bed filled with cenospheres (solid hollow permeable spherical particles). The permeability of cenosphere
walls and the drag coeficient of cenospheres in the gas flow are determined.
