Abstract
ABSTRACT
The present study proposes new technique to implement pressure sensitive coating on
porous anodized aluminum. The new technique is called pressure sensitive foil (PSFoil).
It is based on the conventional anodized aluminum pressure sensitive paint (AAPSP)
technique. In this technique, a very thin aluminum foil is coated with pressure
sensitive paint using anodization method. The resulting pressure sensitive foil (PS-Foil)
can be stick over any flat surface using a very thin silicon layer. The PS-Foil technique
shows very fast time response as conventional porous anodized aluminum and high
spatial resolution compared with conventional PSP binder based techniques. It can also
be applied to any existing model surface without the need to fabricate the model from
aluminum. The total thickness of the aluminum foil and silicon layer is as small as 250
micro-meters. The paint employed in the present research is Bathophen Ruthenium
Chloride (Ru(ph2-phen) or Ru(dpp) ). Commercially available inexpensive, high quality,
14-bit, CCD camera is used to capture the PSP images. Intensity based method and
"in-situ" calibration procedure are used to obtain the calibrated PSP images. The
proposed technique was applied to measure the pressure distribution over a flat plate
due to subsonic jet impingement at different impingement angles. The resulting PSP
images showed high spatial resolution of the pressure distribution and pressure
difference as low as 0.5 kPa can be measured.
