This is beta version 1.0.

This applet is a potential-flow laboratory; a student can build up incompressible, irrotational flows by superposition of a free-stream velocity and various singular solutions to Laplace's equation (sources, sinks, vortices and doublets). Once the flow is built up, the student can visualize the flow, by plotting streamlines, velocity vectors and isopotential lines. The student can also use animation to visualize the flow, seeing how bubbles are convected by the flow, and how a fluid element is convected and deformed. In addition, the local velocity and pressure coefficient are tracked as a function of the mouse location.

Choose **Build New Flow** to build up a flow from its flow
elements. The location of the flow elements can be set with the mouse,
or, if more precision is desired, by entering the coordinates via keyboard
input. Any combination of singularities and free-stream is allowed. A "classic"
combination is that of a free-stream, and a vortex and a doublet at the
origin. This gives the potential flow about a rotating cylinder. After
the flow is built up, the student can analyze the flow, by plotting static
quantities (**Plot Flow Quantities**) or animating the flow with bubbles
or fluid elements (**Animate Flow**). If, at any time, the student wants
to add more singularities to the flow, that can be done by choosing **Modify
Existing Flow**.

This applet was inspired by the PotFlow module of the TODOR software, which was developed at MIT.
