This study used pressure-sensitive paint (PSP) and determined the surface pressure distributions for a compressible swept convex-corner flow. The freestream Mach numbers were 0.64 0.83. angle were, respectively, 10–17° 5–15°. Expansion compression near corner apex clearly visualized. For test case of shock-induced boundary layer separation, there greater spanwise gradient curved shocks. acquire...

We derive a scaling law for the characteristic frequencies of wall pressure fluctuations in swept shock wave/turbulent boundary layer interactions presence cylindrical symmetry, based on analysis direct numerical simulations database. Direct large domains show evidence spanwise rippling separation line, with typical wavelength proportional to bubble size. Pressure disturbances around line are s...

We demonstrate a novel electro-optic swept source for wavenumber-linear interferometric sensing and imaging applications. The electro-optic swept source based on an acousto-optic tunable filter (AOTF) provides high environmental stability and arbitrary drive function sweeping because the electro-optic wavelength selection does not depend on a mechanical moving component to tune the output lasin...

NMR experiments of " B by both field-swept and high-resolution NMR are reported to probe the electric field gradient at boron sites and its distribution in Pyrex glass. Both spectra are successfully interpreted with the same set of parameters. It is stressed that field-swept NMR experiments to observe total powder spectrum can be helpful to get information on electric field gradients and asymme...

This article describes a method to accelerate parallel, explicit time integration of two-dimensional unsteady PDEs. The method is motivated by our observation that latency, not bandwidth, often limits how fast PDEs can be solved in parallel. The method is called the swept rule of space-time domain decomposition. Compared to conventional, space-only domain decomposition, it communicates similar ...

Recent developments in formulations for generating swept volumes have made a significant impact on the efficiency of employing such algorithms and on the extent to which formulations can be used in representing complex shapes. In this paper, we outline a method for employing the representation of implicit surfaces using the Jacobian rank deficiency condition presented earlier for the sweep of p...

At a transonic condition, the design of natural laminar flow (NLF) wing is challenging because extension needs to be finely balanced with potential wave drag increase. To achieve this balance, it proposed unlock sweep and introduce three-dimensional (3-D) contour shock-control bump (SCB) in optimization NLF infinite swept aiming at total reduction. A 3-D Reynolds-averaged Navier–Stokes solver e...
