“…The other approach is the Lagrangian one: particle traces exemplify this. Visualization and hardware were discussed in a paper entitled &dquo;Flow visualization of CFD using graphic workstation&dquo; (Lasinski et al, 1987). The hardware and software environment described there is now commonly available.…”

Several flow visualization techniques using the Lagran gian approach are proposed for analyzing the numerical solutions of unsteady flow fields computed by the Eu lerian approach. We show how these methods can be used to assess the validity of solutions and to extract the nature of the flow fields. The numerical algorithms for the flow solver and the flow visualization are introduced. The incompressible Navier-Stokes equations are solved using the extended MAC method and the compressible Euler equations are solved using the TVD MacCormack method. Most of the flow visualization methods are conventional. For vector fields, however, we introduce a particle tracing algorithm that is suitable for large amounts of numerical data. We present four flow visu alizations using these methods: flow past a circular cyl inder in two dimensions, shock wave propagation over a circular cylinder, flow past a sphere, and flow around an entire automobile.

“…Our experiments were performed at a much larger focal length (1m) than the one used in Ref. 3. As a consequence, the intensity of the beams reflected from the polished aluminum plate, which was used as a wall surface, proved to be rather weak and yielded noisy fringe time records.…”

“…3 The applicability of the techniques quoted is not limited to flows with near-wall similarity of the mean velocity profile, which is required for standard techniques such as the Preston tube or Clauser chart that infer the skin friction from measured velocities. In this Note, a modified version of the laser interferometer method is reported as well as its experimental validation and application in two-dimensional, incompressible, turbulent boundary layers.…”

“…Although computer rendered and printed graphics have existed for decades, true interactive visualization tools have appeared only recently. One of the first recognized visualization programs was Plot3D, which was developed at NASA Ames [13]. Plot3D was a package designed to visualize 3D data from CFD and to allow the user to examine different aspects of their data.…”

Particle based simulations are becoming more common, owing to the maturing of fields such as plasma physics and rarefied gas dynamics and the availability of cheap computing power.Computational power is also making the size of the particle simulations grow. Current simulations now use orders of magnitude more particles than they used just a few years ago. Up until now there had not been any dedicated visualization tools with which to efficiently examine the results of these simulations. This thesis presents the development of Particle3, a particle based scientific visualization package which fills this role. Particle3 is a collection of tools which were developed in order to provide an environment to examine and interrogate particle simulations in three dimensions. In order to simplify the development, Particle3 was based on the paradigm of an existing visualization package named VISUAL3. VISUAL3 is introduced and described. The evolution and development of the Particle3 architecture and tools are described. Finally Particle3 is applied to two simulations in the field of space plasma physics, to demonstrate how it can be used to examine particulate data. The first study examines the effects of probe bias on the Charge Hazards and Wake Shield (CHAWS) experiment and the second case shows the back flow contamination from an ion engine on the ARGOS spacecraft.
