“…Using thin layers of polymer-based LPS-F1 paint, Borovoy et al [78] measured the pressure distribution on a cylinder at Mach 6 in a shock wind tunnel with duration of 40 ms (TsAGI UT-1), and achieved reasonable agreement with the theoretical solution and pressure transducer measurements. The achieved accuracy was about 10 per cent.…”

Abstract:The current paper describes the development of pressure-sensitive paint (PSP) technology as an advanced measurement technique for unsteady flow fields and short-duration wind tunnels. Newly developed paint formulations have step response times approaching 1 ms, making them suitable for a wide range of unsteady testing. Developments in binder technology are discussed, which have resulted in new binder formulations such as anodized aluminium, thin-layer chromatography plate, polymer/ceramic, and poly(TMSP) PSP. The current paper also details modeling work done to describe the gas diffusion properties within the paint binder and understand the limitations of the paint response characteristics. Various dynamic calibration techniques for PSP are discussed, along with summaries of typical response times. A review of unsteady and high-speed PSP applications is presented, including experiments with shock tubes, hypersonic tunnels, unsteady delta wing aerodynamics, fluidic oscillator flows, Hartmann tube oscillations, acoustics, and turbomachinery. Flowfields with fundamental frequencies as high as 21 kHz have been successfully measured with porous PSP formulations.

“…Its application for hypersonic §ows is problematic because of signi¦cant PSP temperature sensitivity. In the present work (see also [18,19]), the problem was resolved (i) by conducting the tests in a short duration wind tunnel; (ii) by manufacturing the model from a heat-conducting material (an aluminum alloy) in contrast to model for heat transfer measurements; and (iii) by applying a fast response PSP.…”

The §ow structure and heat transfer on sharp and blunted plates near a wedge have been studied experimentally at Mach number 6 and two Reynolds numbers corresponding to laminar and transitional boundary layers ahead of the wedge. Similarly to the two-dimensional (2D) §ow, the plate£s blunting causes a decrease of heat transfer at threedimensional (3D) interference between the boundary layer and the shock wave. However, there is a threshold bluntness value beyond which the in §uence is negligible. Heat transfer and pressure measurements as well as surface §ow visualization have been performed by means of panoramic (global) methods based on the use of luminescent coatings. They have been used in a short duration (pulse) wind tunnel for the ¦rst time.

“…The response rate for luminescent paints is proportional to the square of the thickness (44) and traditional methods require very thin paints. The way forward was to increase the porosity by increasing the surface area to volume ratio of the binder and including micro voids (45) .…”

The paper discusses the development and application activities within the Aero-Physics and Measurement Technology Laboratory at the University of Manchester on pressure sensitive paint and thermographic phosphor optical imaging systems for gas dynamic applications. It provides a brief review of the basic principles, fundamental theory, properties, chemical characteristics and bonding technologies associated with the two systems. A number of case studies are presented, which exhibit the range of applicability, limitations and potential for further development of the technologies.
