Gridless Determination of Aerodynamic Loads Using Lagrangian Particle Tracks

Distributed Measurement of Aerodynamic Loads

A method for accurately measuring the drag associated with a protuberance on an aircraft has been devised and implemented in a wind tunnel using a C-130 model. The C-130 aircraft has been heavily modified for various different configurations and the impact that these modifications have had on the aerodynamic performance of the aircraft has not been well documented. This paper describes a method...

Gridless finite-size-particle plasma simulation

The main features of gridless finite-size-particle (FSP) codes are discussed, from the point of view of the performances that can be obtained, with respect both to the spatial-resolution level and the efficiency of parallel particle simulations. It is shown that such codes are particularly suited for particle-decomposition parallelization on distributed-memory architectures, as they present a s...

Aerodynamic Loads on Tall Buildings: Interactive Database

Under the action of wind, tall buildings oscillate simultaneously in the alongwind, acrosswind, and torsional directions. While the alongwind loads have been successfully treated using quasi-steady and strip theories in terms of gust loading factors, the acrosswind and torsional loads cannot be treated in this manner, since these loads cannot be related in a straightforward manner to the fluctu...

Lagrangian Fluid Dynamics using Smoothed Particle Hydrodynamics

Computational fluid dynamics is a hot topic in Computer Graphics. The capability to reproduce realistic fluids numerically has gained an increased interest the last decade. Grid-based methods have been favored the most to solve the mathematical equations for fluid flow, but often they lack the ability to create interactive fluid simulations together with detailed fluid surfaces. Interactive flu...
