A zonal noise prediction method for trailing-edge noise with a porous model
, 2019In this contribution, a hybrid zonal simulation tool with volumetric inflow turbulence forcing is applied to trailing-edge noise of a NACA0012 airfoil with and without a porous insert at representative Mach and Reynolds number of 0.1118 and 1.0 × 106 ...

Interactive 3D Force‐Directed Edge Bundling
Computer Graphics Forum, 2016AbstractInteractive analysis of 3D relational data is challenging. A common way of representing such data are node‐link diagrams as they support analysts in achieving a mental model of the data. However, naïve 3D depictions of complex graphs tend to be visually cluttered, even more than in a 2D layout.

CONTROL OF FLOW OVER A BLUFF BODY
Proceeding of Fifth International Symposium on Turbulence and Shear Flow Phenomena, 2008In this review, we present control methods for flow over a bluff body such as a circular cylinder, a 2D bluff body with a blunt trailing edge, and a sphere.

A career in vortices and edge forces
The Aeronautical Journal, 2012AbstractThis lecture recognises the background and distinguished work of Frederick William Lanchester, and notes that my background has a few similarities with his. These include a shared interest in wings, lift and vortices. My career at the NASA Langley Research Center spans the time-frame from America’s Super Sonic Transport through 2009.

Resistance of plate edges to concentrated forces
Journal of Constructional Steel Research, 1995Abstract The prediction of the resistance of plate edges to concentrated loads has been dealt with in numerous studies of a more or less empirical nature. The normal approach is to use two criteria for the resistance, one based on yielding and one based on instability.

Edge Forces in Contacting Graphene Layers
Journal of Applied Mechanics, 2015Temperature- and stiffness-dependent edge forces offer new mechanisms of designing nanodevices driven by temperature and stiffness gradients. Here, we investigate the edge forces in a graphene nanolayer on a spring supported graphene substrate based on molecular dynamics (MD) simulations.

Surface force measurements at kaolinite edge surfaces using atomic force microscopy
Journal of Colloid and Interface Science, 2014Fundamental results obtained from research on the properties of the edge surfaces of kaolinite particles (~500 nm) are reported. Of particular significance was the development of the experimental protocol. Well-ordered kaolinite edge surfaces were prepared as an epoxy resin sandwich structure having layered kaolinite particles in the center of the ...

Control of turbulent separated flow over a backward-facing step by local forcing
, 1996 An experimental study was made of the flow over a backward-facing step. Excitations were given to separated flow by means of a sinusoidally oscillating jet issuing from a thin slit near the separation line. The Reynolds number based on the step height (H)

Edge sharpness perception with force and contact location information
2011 IEEE World Haptics Conference, 2011The effect of contact location information on the perception of virtual edges was investigated by comparing human edge sharpness discrimination under the force-alone and force-plus-contact-location conditions. The virtual object consisted of the 2D profile of an edge with two adjoining surfaces.
