Abstract:

A technique and results of the experimental study of a drag coefficient of a spherical particle in nonstandard conditions are presented. The effect of the gas injection from a surface of a solid spherical particle on the drag coefficient is analyzed under variations in the ratio of the gas injection velocity and the velocity of airflow around the particle. The dependence of the drag coefficient on the velocity of the gas injection from a particle surface is derived. The influence of the temperature difference between the fluid and particle on the drag coefficient during particle sedimentation in a viscous fluid is studied; the corresponding dependence is found.

Keywords:

drag coefficient, solid spherical particle, gas injection from the particle surface, non-isothermal conditions, gravity sedimentation, viscous fluid
