This paper presents some tools that have been developed to aid in visualizing the analysis results obtained from the simulation of coal combustion furnaces in the particular and other computational fluid dynamics problems in general. These tools have been implemented into a visualization software package called CQUEL.BYU. This paper presents an overview of the general capabilities of CQUEL.BYU that are pertinent to the coal combustion community. It then presents some new algorithms for visualizing gas flow, particulate motion, and scalar fields using animation techniques. Specifically, many kinds of flow features, such as vortex formation and velocities at each point, can be conveyed effectively in both animation and still images by means of cyclic particle animation and oriented motion blur. Implementation of these capabilities into a software package that runs on most general purpose, low-cost workstations is discussed.

As the cost of computational power decreases, more and more algorithms appear which model physical processes using digital computers rather than physical scale models or experiments. Many of these algorithms use discrete approximation methods to solve a continuous problem. The complexity of these algorithms has increased also, as computational power has increased, from hundreds of data points to a million or more, and from two dimensions to three.
Many engineering applications suffer from a lack of adequate presentation graphics that makes the interpretation of the analytical data, described above, difficult. Trends and patterns are more easily observed in graphical form when compared to reviewing tabulated data. In engineering applications, color and shading may be used to realistically portray an object and also to present additional information about it through the use of distorted shapes and color coding to classify such functions as temperature, pressure, species concentrations, etc.
The programs, described in the following sections, address the issue of visualization of finite element and finite difference data. They reflect the effort of numerous researchers over a period of approximately twenty years.
