Aerodynamic drag of a circular cylinder in transverse flow of gas suspension is experimentally investigated. Experiments were conducted in a wind tunnel with flow rate ranged from 0.01 to 2.7 kg/s. Powders of 4000 kg/m³ density were used as solid. Investigation of parameters of two-phase working flow showed the nonuniformity along the middle cross section of the model for speed profile of bearing phase (air) being better 2 to 3 percent, solid particle velocity less than 3 to 4 percent, and discrete phase density 8 to 10 percent. Introduction of solid impurity into gas flow with Reynolds number equal 10⁵ results in decreasing in cylinder resistance. Empirical formula is proposed to define main parameters influencing the body resistance in flow of gas suspension.
