Journal ArticleDOI
A review of pressure-sensitive paint for high-speed and unsteady aerodynamics
TL;DR: In this paper, the development of pressure sensitive paint (PSP) technology was described as an advanced measurement technique for unsteady flow fields and short-duration wind tunnels, which has resulted in new binder formulations such as anodized aluminium, thin-layer chromatography plate, polymer/ceramic, and poly(TMSP) PSP.
Journal ArticleDOI
A review of Backward-Facing Step (BFS) flow mechanisms, heat transfer and control
TL;DR: It is shown that the step size (duct expansion ratio) will define the basic re-circulation and re-attachment process, while the coupled effects of inflow parameters and the perturbation designs also help shape the flow behaviors after BFS.
Journal ArticleDOI
Adsorptive pressure-sensitive coatings on porous anodized aluminium
TL;DR: In this paper, a novel pressure-sensitive luminescent coating on porous anodized aluminium is developed, which is suitable for measuring unsteady pressure fields due to its fast-responding characteristics.
Journal ArticleDOI
Image measurements of unsteady pressure fluctuation by a pressure-sensitive coating on porous anodized aluminium
TL;DR: In this paper, a pressure-sensitive luminescent coating on porous anodized aluminium (AA-PSP) was applied to measure non-periodic unsteady pressure distribution on a wind-tunnel model.
Proceedings ArticleDOI
Surface pressure measurement in a cryogenic wind tunnel by using luminescent coating
TL;DR: In this article, a 14-thick bump model was tested in the 0.1m Transonic Cryogenic Wind Tunnel at NAL and two intensity images were acquired, one taken at low speeds and the other taken at high Mach numbers.
