“…These techniques indicate the presence of a saddle point in the flow near the top, center of the geometry (See Helman and Hesselink [5] or Post et al [12] for a more thorough description of flow topology). The deviance from the ideal tumble motion is a result of a trade-off made in the design of the intake port, as its shape must also allow enough incoming fresh air to mix with fuel.…”

Figure 1: Visualization of swirl and tumble flow using a combination of direct color-mapping, streamlines, isosurfaces, texture-based flow visualization and slicing. (Left) visualizing swirl flow using 3D streamlines and texture-based flow visualization on an isosurface, (middle-left) a clipping plane is applied to reveal occluded flow structures, (middle-right) an isosurface and 3D streamlines visualize tumble motion, and (right) the addition of texture-based flow visualization on a color-mapped slice. ABSTRACTWe investigate two important, common fluid flow patterns from computational fluid dynamics (CFD) simulations, namely, swirl and tumble motion typical of automotive engines. We study and visualize swirl and tumble flow using three different flow visualization techniques: direct, geometric, and texture-based. When illustrating these methods side-by-side, we describe the relative strengths and weaknesses of each approach within a specific spatial dimension and across multiple spatial dimensions typical of an engineer's analysis. Our study is focused on steady-state flow. Based on this investigation we offer perspectives on where and when these techniques are best applied in order to visualize the behavior of swirl and tumble motion.

“…Flow visualization methods visualize the results of flow simulation by drawing arrows or streamlines [Turk and Banks 1996], texture-based methods by applying flow patterns to random texutures [Cabral and Leedom 1993;Laramee et al 2004], geometric methods by extracting geometric objects such as streamlines or stream surfaces [McLouglin et al 2010], and feature-based methods by visualizing physically meaningful parts such as vortices [Post et al 2003]. These techniques rely on offline simulation results and can provide accurate visual effects.…”

This paper presents a lightweight sketching system that enables interactive illustration of complex fluid systems. Users can sketch on a 2.5-dimensional (2.5D) canvas to design the shapes and connections of a fluid circuit. These input sketches are automatically analyzed and abstracted into a hydraulic graph, and a new hybrid fluid model is used in the background to enhance the illustrations. The system provides rich simple operations for users to edit the fluid system incrementally, and the new internal flow patterns can be simulated in real time. Our system is used to illustrate various fluid systems in medicine, biology, and engineering. We asked professional medical doctors to try our system and obtained positive feedback from them.
