Abstract
A new technique for measurement of the drag coefficient of spherical particle at condition of gas injection from its surface is presented. Results of investigation of the effect of the gas injection from a surface of a solid spherical particle on the drag coefficient are presented. In the investigation, the ratio of the gas injection rate and the velocity of the flow blowing around the particle was varied. Based on the obtained results, it is shown that the drag coefficient in condition the absence of the gas injection from the particle surface in the examined range of the Reynolds numbers are consistent with the standard drag dependence for the turbulent flow regime. At the same time, when at condition of gas injection from the particle surface, the drag coefficient is decreased (this effect is more pronounced with a decrease in the flow rate). The dependences of the change in the drag coefficient on the Reynolds number with changing the rate of the gas injection from the particle surface.
