Research on the view quantization method of flow visualization based on effective information

As an important means to observe the internal mechanism of fluid and analyze the change principle of flow, the flow visualization realizes the purpose of more intuitive observation of flow field and deep analysis of the change principle of flow by simulating the flow data. In this paper, the development status, and the deficiency of theory and practice of flow visualization is analyzed, and the problems and requirements of flow visualization are summarized. Effective information - a quantization standard of measuring visualization view is proposed. Meanwhile, the definition, application method and calculation process needed to construct the quantization method are given, and the application details of the quantization method are illustrated by the numerical realization of these definitions in a sample flow data. Finally, the performance of visualization method based on effective information is analyzed in terms of applicability, extensibility and computability, and the defects and shortcomings of this method are pointed out. The method of this paper is designed to provide a good supporting role for the visualization element placement method, and to service for the design of new flow visualization methods, and it also is helpful to design new flow visualization methods.
