There are two flow tube facilities in AANTC to study the effects of grazing flows on acoustic liners. Impedance eduction methods are conducted for different types of sound absorption materials. The dimensions of tubes a…
View recordThe low-noise low-speed wind tunnel contains two test sections. Both sections have a cross-section of about 2.5 m wide and 2 m high and the test wind speed ranges from 15 m/s to 40 m/s. In aerodynamic test section, a mo…
View recordhe anechoic wind tunnel houses an open-jet inflow duct of 0.4m (W) by 0.4m(H), and an outlet that has a cross-section of 0.6m (W) by 0.6m (H). The test section is enclosed within an anechoic chamber that has dimensions …
View recordWe use a high-order Linearised Euler Equation (LEE) solver to study specific aeroacoustic problems that are not governed by nonlinear and viscous effects. An LEE solver is significantly faster than a Navier-Stokes solve…
View recordWe use a high-order Euler solver to study aeroacoustic problems that have nonlinear physics. In the video, the Euler solver shows what happens when a turbulent field impinges on the leading edge of a transonic aerofoil.…
View recordThis facility was designed and fabricated at HKUST, and it is used to evaluate prototype acoustic materials. Test samples are sandwiched tightly between two paralleled Plexi glass plates (2.4 m x 1.2 m x 0.02 m), which …
