Abstract:

A computer program for displaying flow-field color contour plots, generated from computational fluid dynamics CFD solutions, has been developed by extending the contour plotting option of the GENPLOT routine of Dr. R. G. Hindman. An algorithm for generating color-filled contour regions was developed for this extension and is described. The algorithm performs a detailed examination of the behavior of the dependent variable within the plotting domain to generate the contour regions and determines the relationship between these regions and their associated contour levels to assign the appropriate fill color to a particular region. Flow-field color contour plots generated from a hypersonic viscous shock-layer computation, a supersonic viscous blunt-fin computation, and a hypersonic viscous gas jet nosetip computation are presented to illustrate the capabilities and flexibility to the routine and to demonstrate that they can be used to aid the interpretation of CFD results.
