Acoustic methods applied to opaque systems have attracted the attention of researchers in
fluid mechanics. In particular, owing to their ability to characterise in real-time, non …

A quantitative synthetic Schlieren imaging (SSI) method based on fast Fourier demodulation
is presented. Instead of a random dot pattern (as usually employed in SSI), a 2D periodic …

We present a benchmark study of Optical Flow (OpF) methods for fluid mechanics
applications. It is aimed at assessing the performance of three OpF methods, Lucas and …

This paper describes OpenOpticalFlow_PIV, an open source Matlab program integrating the
optical flow method with the cross-correlation method for extraction of high-resolution …

In this study, we propose a deep learning-based spatial refinement method to provide robust
high-resolution velocity fields for particle image velocimetry (PIV) analysis. We modified the …

A hybrid method for particle image velocimetry (PIV) is developed to overcome the
limitations of the optical flow method applied to PIV images with large displacements. The …

In this study, we propose a method to enhance the particle image velocimetry (PIV) velocity
resolution using global optical flow along with image warping. A global optical flow formula …

Clean and efficient combustion of liquid fuels depends on spray fineness that aids fast fuel
vaporization and better fuel–air mixing. Swirl-burst (SB) atomizers generate fine droplets at …

The traditional approach to the interpretation of spirals observed in radar, optical and
radiometric panoramas of a sea surface is based on equating the outer spiral scale with the …

High spatial resolution and high accuracy estimation of 3D velocity fields are important for
tomographic particle image velocimetry (Tomo-PIV), especially when measuring complex …
