Although only this airfoil profile was investigated, it was selected because it has been employed in several wing-in-ground effect studies [19, 21, 22, 23], and has a flat pressure surface (similar to the Clark Y airfoil profile) which provides a reasonably uniform offset from the diffuser ramp.
It is shown in Figure 7 that the static pressure on pressure surface is higher than that on suction surface, and the pressure difference causes the moment of resistance on rotating impeller.
Increased suction on suction surface and increased pressure on pressure surface are clearly noticeable on installation of GF, which results in lift enhancement.
The results of Ames [11-13] with four turbulence intensities (1%, 7.5%, 8%, and 12%) showed that turbulence length scale had significant influence on the HTC at stagnation zone and the pressure surface. Turbulence also decreased the effectiveness of shower-head film cooling.
From the performance curves; it is found that pressure surface squealer tip configuration show increased energy coefficient and efficiency across the compressor compared to other configurations.
The mass averaged values of total pressure coefficient ([[psi].sub.o2]) and static pressure coefficient ([[psi].sub.s2]) at the impeller exit for three configurations at three flow coefficients clearly indicate increase in total and static pressure for pressure surface squealer tip configuration compared to other configurations.
New for 2007, this lying surface will raise and lower electrically to provide an alternating pressure surface.
The high-frequency sensor signals are transmitted through films embedded under the pressure surface of the blades.
The hydraulic loss increases because the flow hits the pressure surface of OGV blades.
After checking the blade line, it shows that there are no reflection points on pressure surface and suction surface.
These are the kind of chiseled squiggles that usually evoke our atmospheric pressure surfaces and topographical maps, and I am in a renewed aesthetic bliss just looking at them.
