The effect of low-frequency pulsations of gas on the motion 
of solid particles has been studied on the basis of numerical solution 
of equations of the dynamics of a monodisperse gas suspension with 
account for interphase forces of hydrodynamic drag, virtual masses, 
and forces due to nonstationary effects around particles. It is found 
that at certain parameters gas pulsations lead to enhancement of interphase 
heat transfer. The dependences of the time of particle residence in 
a pneumochannel on the frequency of gas pulsations have been obtained.
