Abstract: As the main research direction which earliest developed and most widely used in the field of scientific visualization,flow visualization plays an underlying role in helping users analyze and comprehend complex flow mechanism,provide insight into flow physical phenomena and discover flow scientific laws.And perception enhanced flow visualization as one of flow visualization methods,can show effectively the flow field structure characteristics,the interactions among various properties and complex flow physical phenomena,and it provides a favorable flow field visualization analysis environment to improve processing efficiency of flow scientific data and visual analysis ability.In this paper,we mostly introduce the applications of perception enhanced flow visualization methods in a variety of areas,such as industrial design,aerospace,biomedicine and some cross-domain applications.A top-down VCIH model for flow visualization and analysis drawing from the experience of domain experts by analyzing flow physical phenomena and having an insight into the complicated physical regularities of flow field.This model includes vision,cognition,interaction and hardware.According to the VCIH model,then we summarize visualization methods based on perception enhanced from four aspects:enhancement of visual perception,enhancement of flowphysical process,enhancement of exploratory interaction and enhancement of hardware dependencies.Finally,we discuss future development trend of those topics combined with application demand.
