On the basis of computer experiments, the analysis of cylindrical capillary-porous material’s aerodynamic characteristics in a pulsing gas flow have been carried out. It is shown that the nature of airflow around a single particle is different in stationary and pulsing flow. Particle’s aerodynamic characteristics heavily depend on frequency of vortexes separation from the particle’s surface and the configuration of the vortex street itself. Three universal specific zones of dimensionless external flow pulsation’s frequency influence on vortex separation frequency have been discovered. In the first zone the influence is either small or is absent. In the second zone the dimensionless frequency of vortexes detachment decreases with the increasing of flow’s pulsation frequency until they both become equal. In the third zone, the frequencies of flow’s pulsations and vortexes detachment are equal (the lock mode). In all the zones the frequency of vortexes pair detachment is equal to the lift force’s pulsations. The amplitude of these pulsations characterizes the vortexes intensity at the moment of their detachment. It is shown that in the first zone and till the moment of synchronization the variable amplitude of lift and drag forces coefficients pulsations depends on form of flow’s pulsations. In these zones the frequency of lift force’s pulsations inside one fluctuation period of flow’s velocity also is a variable which reaches its peak at the amplitude value of velocity. The discovered influence of pulsating gas flow on the amplitude and frequency of lift coefficients fluctuations witnesses about a possibility of its usage for controlling the aerodynamic characteristics of particles by means of influencing the intensity and frequency of vortexes detachment and the form of Karman’s vortex street.
