Visiometric analysis of ratcheting is an application of computer visualization and animation to an experiment in combustion. In the experiment, a flame front is established over a circular porous plug burner at low pressure. As the flow rate is increased, the flame front exhibits a variety of spatial and temporal phenomena ranging from steady patterns to highly disordered behavior. In the parameter range of interest, the flame front forms patterns consisting of concentric rings of cells. A ratcheting motion is observed in which one or more rings of cells slowly rotate (ß 1 deg/sec), speeding up and slowing down in a complicated manner which cannot be discerned from direct observation. This paper describes visualization and analysis of the motion of the individual cells and the development of measures of motion rigidity within the rings. Frames of videotape are digitized and individual cells are tracked by programs developed under the Khoros 2 image processing environment. The tracking ... |
