AI Technical Summary
Existing technologies make it difficult to directly measure the torque coefficient of cylindrical particles under the action of external airflow in a fixed posture, which affects the study of particle orientation, stability and motion trajectory.
A device was designed that includes a gas supply and regulation system, a cylindrical test cylinder system, a particle attitude adjustment system, a torque measurement system, and a pressure monitoring system. By fixing the cylindrical particles at any angle under stable and adjustable airflow conditions, the torque coefficient is calculated by measuring the force difference between the two ends of the particles.
The torque coefficient was measured at different Reynolds numbers and angles, providing experimental basis for the study of aerodynamics of cylindrical particles. The device has a simple structure, is easy to operate, has low cost, and provides high accuracy in measurement results.
