Experimental Apparatus
Our laboratory houses a large wind tunnel (Guettingen type, velocity range: xx - xx m/s) for testing a small wing model, which we do for an undergraduate course. We also use Kanomax PIV (particle-image-velocimetry) laser and Dantec LDV (laser-doppler-velocimetry) systems to quantitatively study the gas flow. Three high-speed cameras (Nac hx-7 x2 and Photron SA5 x1) are key facilities we heavily rely on to visualize both gas/underwater flows. The optical setups for monochrome/color schlieren/shadowgraph are also available. The dual-laser system allows us to study the bubble-bubble interaction with fine-tuning. We also use other pieces of equipment including (but not limited to) gas compressors, vacuum pumps, omnidirectional underwater hydrophones/condenser microphones, an optical microscope, DSLR cameras with flash bulbs, load cells, and acceleration pick-ups.
We also perform numerical simulations with the support of 16-core high-end computers and Ansys Fluent Software.
