Abstract

Abstract: Flow is one of the most fundamental phenomenon in natural world. Flow visualization can give an intuitive view of flow fields and contribute to the observation and analysis of flow. Real flow fields are all dynamic while traditional visualization approaches are not able to reflect the trends of flows or the diversity inside them. Based on the research of Lagrangian Coherent Structures in Computational Fluid Dynamics, the concept of flow field topology was redefined, two typical 2D dynamic vector fields were selected for topology analysis, and the results were used to optimize the visual effects of geometric visualization. Experiments show that visualization of 2D dynamic vector fields based on topology analysis can extract the coherent structures of flows which are helpful to the comprehension of flow for researchers and description of characteristic difference inside flows.
