Particle Seeded Grains to Identify Highly Irregular Solid Boundaries and Simplify PIV Measurements
2019
Frontiers in Earth Science
Particle image velocimetry (PIV) is a non-invasive technique for measuring velocity fields. It is especially powerful when coupled with refractive index-matching (RIM) to map velocity fields around solid objects. The solid objects are typically removed from the flow field with a masking approach before performing the PIV analysis and mapping the velocity field, thus defined as an a priori method. However, applying this method, with a mask of the correct shape and at the correct location, is
