Dynaflow

Dynamic Flow has released 2DFlow, a program for visualising flows induced by the distributions of point and line singularities such as vortices, dipoles and sources.

The software, designed for professional and educational use, graphically illustrates the use of potential flow theory through a combination of background fluid flow and a variety of singularities to simulate a wide range of fluid mechanics problems (e.g. flow past cylinders, rankine bodies, hydrofoils, bluff bodies, etc.). 2DFlow uses a graphical user interface with easy access to its commonly used functions and features. 

The company states that when used in conjunction with a fluid dynamics classes, 2DFlow can make visualisation and comprehension of textbook theory as easy as clicking the mouse.  Since, 2DFlow can also be used to simulate and visualise complex potential flows, it serves as a valuable tool for an engineering professional.

  • Highlights of the software include:

  • Point-and-click singularity insertion and editing.

  • Solid boundaries and objects of arbitrary shapes can be inserted in the flow.

  • Study internal as well as external flows.

  • Problem simulation that allows the user to compute and view Flow-Trajectories, Equipotential-Lines, Stream-Lines, Pressures and Velocity Vectors using full-color contours, iso-quantity lines and trajectories.

  • Circulation and Force computation along a user defined elliptical or rectangular area and Flux computation along a user defined line. 

  • Particle and Strain-Element Emission from arbitrary regions in the flow-field.

  • Graphical representations of flow quantities.

  • Interactive Animation of the flow-field using scalar particle distributions and allowing motion of inserted vortices.
