Visualization of computer-generated flow fields

Abstract

Flow field variables are visualized using color representations described on surfaces that are interpolated from computational grids and transformed to digital images. The color at a point on a surface represents the magnitude of a variable, and several surfaces can be included in a single digital image. Typically the surfaces are a boundary surface, a windward surface, and a crossflow surface. Sequences of images, in pictorial form, are presented to describe an entire flow field or a time history of a flow field. Several examples are presented.
