论文摘要
本研究报告了使用智能手机摄像头在环境光中,而不是高科技设备(如专业相机和高功率激光/ LED)对表面流量轮廓进行了PIV分析。此外,它提供了一种逐步的方法,用于优化在磁性搅拌器不同旋转频率下生成的涡流流量的记录速度和询问窗口大小。优化方法已经用磁性搅拌器产生的涡流流的示例进行了解释。该分析是使用基于MATLAB的应用程序PivLab进行的。最后,已将优化参数与汉堡涡流模型进行了比较,该模型与PIV数据显示了很好的一致性。所提出的方法还可以确定不透明液体的肯定表面流。
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.
