Visualization of Turbulent Flow by Spot Noise
Turbulent flow is often modelled using statistical models. In these models the flow is described using average velocity at a certain level of scale, and velocity variations at smaller scale are described by some quantity indicating turbulence intensity. In this paper several methods are described which utilize spot noise texture to visualize turbulent flow modelled in this way. With spot noise the separate fields are combined in one visualization which shows both data fields and how they are related in an intuitively clear way. Different aspects of turbulent flow can be shown using different mappings. The utility of this approach will be shown in two hydrodynamical case studies.
