Multi-modal capabilities can be added to a simulation system in order to enhance data comprehension. We describe a system for adding sonification capabilities to a real-time computational fluid dynamics (CFD) simulator. Our system uses Max/MSP modules to add sonic properties to CFD solutions. The enhancements described in this paper allow users to locate sound sources in a 3–D environment using...

The supersonic aerodynamic coefficient of a sphere that represents a broken piece of structure under explosion was obtained by using Computational Fluid Dynamics (CFD).The computer that was used in this study was self-made cluster type parallel machine and available maximum number of CPU was 128. The CFD software named CFD++ was used in this study. CFD++ is general purpose CFD software to solve...

conclusion both techniques provided quantitatively consistent results of in vivo velocity vector fields in right internal carotid artery (rca). pc mri represented a good estimation of main flow patterns inside the vasculature, which seems to be acceptable for clinical use. however, limitations of each technique should be considered while interpreting results. subjects and methods mr imaging was...

High-end computing and computational fluid dynamics (CFD) have played a key role in improving and enhancing Shuttle performance, reliability, and safety for more than two decades. The NASA Advanced Supercomputing (NAS) Division has been developing CFD-based highfidelity design and analysis tools, which are being employed to help analyze today’s problems, as well as guiding design decisions for ...

A local proper orthogonal decomposition (POD) plus Galerkin projection method is applied to the unsteady lid-driven cavity problem, namely the incompressible fluid flow in a twodimensional box whose upper wall is moved back and forth at moderately large values of the Reynolds number. Such a method was recently developed for one-dimensional parabolic problems. Its extension to fluid dynamics pro...

Terrorist attack in buildings by chemical and biological agents (CBAs) is a reality in our lives. This study applies computational fluid dynamics (CFD) to predict CBA dispersion in an office building in order to find the best locations for CBA sensors and to develop effective ventilation systems to protect building occupants in case of indoor CBA releases. It is found that the CFD is a useful t...

Planar laser-induced fluorescence (PLIF) of nitric oxide is used to measure a component of the velocity field for the Mach 7 flow around a cone. Velocities are measured in the freestream, shock layer, and the separated region behind the cone. The measurements are compared with computational fluid dynamics (CFD) codes. The comparison indicates that the CFD correctly predicts the flow over the fo...

Abstract: This paper presents a combination of a computational structural dynamics (CSD) and high fidelity unsteady computational fluid dynamics (CFD) analysis. Regarding a helicopter in hover, aerodynamic loads are computed from the three-dimensional Navier-Stokes solver in overlapped grids, and blade motions are obtained from the geometrically exact rotor beam analysis. To couple those analys...
