Low speed flow separation over a wall-mounted hump, and its control using steady suction, were studied experimentally in order to generate a data set for a workshop aimed at validating CFD turbulence models. The baseline and controlled data sets comprised static and dynamic surface pressure measurements, flow field measurements using Particle Image(More)
An oscillatory zero net mass flow jet was generated by a cavity-pumping device, namely a synthetic jet actuator. This basic oscillating jet flow field was selected as the first of the three test cases for the Langley workshop on CFD Validation of Synthetic Jets and Turbulent Separation Control. The purpose of this workshop was to assess the current CFD(More)
We propose a method to simulate a-Si and a-Si:H using an ab initio approach based on the Harris functional and thermally-amorphisized periodically-continued cells with at least 64 atoms. Hydrogen incorporation was achieved via diffusive addition. In preparing samples that may simulate the distributions of atoms in the amorphous materials, simulated(More)
We present MMT/Megacam imaging in Sloan g and r of the extremely low luminosity Boötes II MilkyWay companion.We use a bootstrap approach to perform robust measurements of, and to calculate uncertainties on, Boötes II’s distance, luminosity, size, and morphology. Comparisons with theoretical isochrones and empirical globular cluster fiducials show that(More)
Arrays of refractive microlenses, with diameters on the order of hundreds of micrometres, have been the subject of much research in the applied physics community [1]. Recently, arrays of optical dipole traps, with 50 µm separation, each containing on the order of 100 laser cooled atoms, have been created [2]. This state-of-the-art experiment,(More)
