Particle Image Velocimetry study on the formation of gas bubbles and electrolyte velocity due to electrochemical reactions for different distances between the electrodes of Flooded Lead_ Acid batteries

Target flow field reconstruction based on dual tree complex wavelet transform and optical flow

“…On the other hand, Particle Image Velocity (PIV) is a transient, multi-point, non-contact Fluid mechanics velocity measurement method. This type of method [11] often performs cross correlation calculation in Fourier domain, and uses surface fitting method to achieve sub-pixel positioning, so the interpretation accuracy is good. As described in references [12][13], the PIV algorithm obtains more complete large-scale features of the target flow field fingerprint image than the DIC algorithm, and the internal structure of the airflow fluid is closer to the real data.…”
