| description | This study investigates the movements of particles in an accelerated toroidal flow channel filled with water, with specific applications for a particle imaging velocimetry gyroscope (PIVG). We used computational fluid dynamics (CFD) to simulate particle behavior under different angular accelerations. These angular accelerations were 4 rad/s<sup>2</sup>, 6 rad/s<sup>2</sup>, and 8 rad/s<sup>2</sup> for particles densities of 1100 kg/m<sup>3</sup>, 1050 kg/m<sup>3</sup>, and 980 kg/m<sup>3</sup>. An examination was performed on the particles’ concentration distribution, velocity profiles, and displacement patterns with respect to the toroidal geometry, which had a volume fraction of 1.5% and was sized at 50 microns. Our results show that particle density significantly affects behavior and displacement within the toroidal flow, with heavier particles (1100 kg/m<sup>3</sup>) settling more quickly and concentrating near the lower z values over time, while lighter particles (980 kg/m<sup>3</sup>) maintain a more uniform distribution. This understanding is crucial for optimizing PIVG accuracy and reliability. |
