During my M.Sc. in mechanical engineering at the University of Campinas. I carried out experiments using a 2D PIV system to measure turbulent water flows that pass over triangular shapes, in order to explain the existence of rippled granular beds that are commonly found in many environmental applications. We understood the instabilities of these beds and the formation of sequences of ripples with slightly rounded edges in closed conduits by tracking the spatial evolution of the turbulent stresses.

I used the Refractive Index Matching (RIM) technique in order to measure the fluid flow around the particles inside Narrow Fluidized Beds (NFB). I am currently developing some scripts to compute the fluid behavior around the particles by using an Eulerian approach (PIV) and to detect and track the particles (black holes in the video shown on the right) by using a Lagrangian approach.
