Aerodynamic effect of an alula-like vortex generator using pressure sensitive paint technique

Study of Trailing-Edge Cooling Using Pressure Sensitive Paint Technique

An experimental investigation was conducted to study the effects of blowing ratio and the existence of lands on the film cooling effectiveness of a turbine blade trailing-edge model. Instead of using a temperature-based technique, a mass transfer analogywas used to quantify the film cooling effectiveness. This was done through themeasurement of the distribution of oxygen concentration over the ...

Pressure-Sensitive Paint: Effect of Substrate

There are numerous ways in which pressure-sensitive paint can be applied to a surface. The choice of substrate and application method can greatly affect the results obtained. The current study examines the different methods of applying pressure-sensitive paint to a surface. One polymer-based and two porous substrates (anodized aluminum and thin-layer chromatography plates) are investigated and ...

Accuracy of Pressure Sensitive Paint

Uncertainty in pressure sensitive paint (PSP) measurement is investigated from a standpoint of system modeling. A functional relation between the imaging system output and luminescent emission from PSP is obtained based on studies of radiative energy transports in PSP and photodetector response to luminescence. This relation provides insights into physical origins of various elemental error sou...

Dipping Deposition Study of Anodized-Aluminum Pressure-Sensitive Paint for Unsteady Aerodynamic Applications

Pressure-sensitive paint technique for surface pressure measurements in a low-density wind tunnel

ABSTRACT A low-density wind tunnel called the Mars wind tunnel, has been developed at Tohoku University that can produce a high subsonic flow at low pressures for aerodynamic measurements of low-Reynolds-number aircraft wings aimed at developing aircraft applicable to the atmosphere on the planet Mars. Accurate surface pressure measurements on the wing are essential for analysis of not only aer...
