This paper presents a computational investigation of a tangential slot blowing conccpt for generating lateral control forces on an aircraft fuselage forcbody. The effects of varying both the jet width and jet exit velocity for a fixed location slot are analyzed. This work is aimcd at aiding rrscarchcrs in designing future experimental and compm tational models of tangential slot blowing. The pr...

Recent developments in strategies and software tools for overset structured grid generation and domain connectivity are described. A scripting approach based on a library of grid generation script macros is adopted to speed up the grid generation process. Advances in this method involve the development of high level functions that encapsulate more complex grid generation tasks. Sample applicati...

Abstract With the growing importance of renewable energy, interest in energy-harvesting technologies based on flow-induced vibrations airfoils has been rekindled past few years. Compared to conventional turbines, these devices are centrifugal stress-free and hence they structurally more robust. They also environmentally friendly due relatively low speeds, thus reducing impact flying animals. In...

The objective of the present work is to discuss the development of a 3D Unstructured-Overset grid Computational Fluid Dynamics (CFD) solver on General Purpose Graphics Processing Units (GPGPUs). As an extension of our previous work on 2D/3D overset grid computations for compressible/incompressible ows on static grids[1][2], the current paper focuses on moving overset grids with dynamic domain c...

A new numerical finite difference code has been developed to solve a thermal convection of a Boussinesq fluid with infinite Prandtl number in a three-dimensional spherical shell. A kind of the overset (Chimera) grid named “YinYang grid” is used for the spatial discretization. The grid naturally avoids the pole problems which are inevitable in the latitude-longitude grids. The code is applied to...
