Scarano, F. (author), Ghaemi, S. (author), Alp Caridi, G.C. (author), Bosbach, J. (author), Dierksheide, U. (author), Sciacchitano, A. (author) The flow-tracing fidelity of sub-millimetre diameter helium-filled soap bubbles (HFSB) for low-speed aerodynamics is studied. The main interest of using HFSB in relation to micron-size droplets is the large amount of scattered light, enabling larger-scale three-dimensional experiments by tomographic PIV. The assessment of aerodynamic behaviour...
