Reconstruction Methods and Application of Computational Fluid Imaging Technology
Computational fluid imaging (CFI) technology is an excellent tool for comparing numerical simulations with wind tunnel experiments of flow. Key methods including reconstruct computational fluid shadowgragh, schlieren and interferogram with numerical simulation technologies. Complex turbulence simulation, trilinear interpolation and flow image reconstruction etc. are developed. CFI technology is used for computational images reconstruction of the three-dimensional complex flow around an obstacle in the shock tube, and results are compared with those from bidirectional holographic experiments. It is shown that CFI can be used in reconstructing patterns of flows with complex geometric boundaries, the zonal area and unsteady characteristics etc., and it may be adopted not only for analyzing flowfield structures, but also for comparing numerical simulations with wind tunnel experimental results.
