離散的流速データから全流速場を復元するためのCFD推定法の開発 Development of CFD Presumption Method to Restore Whole Flow Field from Discrete Velocity Data
Velocity vectors obtained by PIV are distributed discretely depending on the number density of the tracer particles seeded in the flow. In order to estimate the detailed whole-field flow structure from the data, an estimation algorithm to restore the whole-field flow has been proposed using Laplace Equation and velocity correction potential. The performance of the algorithm was examined for two-dimensional vortex flow. The correct restoration rate was evaluated quantitatively by two-dimensional correlation coefficient for the stream function. The results reveal that the present method is applicable for various conditions of discrete PIV data to predict the whole-field flow structure.
