A short Wind Tunnel preview Posted on 1 December 2020 by Lorenzo Raffaele The first Wind Tunnel campaign of HyPer SMM has just finished! While I am postprocessing the huge amount of data we acquired, I would like to share a small video captured with a GoPro inside the test section. Windblown sand saltation is amazing! https://hypersmm.vki.ac.be/wp-content/uploads/2020/12/WT.mp4
