Optimizing recording speed and interrogation window for rotating flow recorded in the ambient light: PIV analysis

Fluid Dynamics 2022-10-11 v1

Abstract

The present study reports PIV analysis of the surface flow profile using a smartphone camera in ambient light instead of high-tech equipment like a professional camera and high-power laser/ LEDs. Additionally, it provides a stepwise method for optimizing recording speed and interrogation window size for the vortex flow generated at different rotational frequencies of the magnetic stirrer. The optimization method has been explained with an example of the vortex flow generated by a magnetic stirrer. The analysis has been carried out using the Matlab-based application PIVlab. Finally, the optimized parameters have been compared with the Burger vortex model, which shows good agreement with the PIV data. The proposed method can also determine the sureface flow of opaque liquids.
