A Visualization Method Based on Discrete Flow Field Continuity Problem
Luo Xiaoxia, Yuan Yafei, Jia Pengtao · 2018
The visualization of flow field is based on the continuity of the fluid motion. But under normal circumstances, the methods of obtaining flow field data are different, resulting in uneven data distribution and errors, cause discontinuity phenomenon in the flow field. For discrete flow field data, this paper uses the method of eigenvector direction to detect the abnormal data of discrete flow field. According to the criterion of “similarity in the space field vector”, the data are repaired to solve the non-uniformity existing in the flow field. By The numerical simulation, the experiment shows the continuous visualization of the eigenvectors of each data point is conducive to the objective representation of the discrete flow field visualization.
