Computational fluid imaging for iodine fluorescence in compressible flows

摘要

Computational Fluid Imaging (CFI) is a new field developing out of computational fluid dynamics (CFD). The effort described herein is the development and validation of a scheme for numerically imaging planar laser-induced iodine fluorescence in a compressible flow. The pressure and temperature required for the calculation of the fluorescence intensity are computed using a SPARK three-dimensional Reynolds averaged Navier-Stokes code developed at NASA Langley. The details of the fluorescence model are included herein and a comparison between a calculated image and an experimentally acquired image is shown.
