Laser Sheet Scattering and the Cameras' Positions in Particle Image Velocimetry
TL;DR: In this article, simulations of laser sheet scattering by microparticles, based on the generalized Lorenz-Mie theory for the case of numerous random spatial distributions of scattering particles, were done, using the novel computational time saving strategy.

Numerical simulation of aerodynamic noise and noise reduction of range hood
TL;DR: In this paper, the hybrid CAA (Computational Aeroacoustics) method is used to numerical study on the aerodynamic noise of a certain range hood, and the results showed that the range hood noise mainly concentrated on low and middle frequencies and characterized by discrete noise.

Digital Particle Image Velocimetry
Christian Willert,Morteza Gharib +1 more
TL;DR: In this article, the directional ambiguity associated with PIV and LSV is resolved by implementing local spatial cross-correlations between two sequential single-exposed particle images, and the recovered velocity data are used to compute the spatial and temporal vorticity distribution and the circulation of the vortex ring.
