The purpose of this tutorial is to illustrate:
- The action of the velocity field over a closed material contour by using the vector field manipulation application. The user can type the desired equations for the velocity field, then chose the Draw Contour option from the drop down box, then input a closed contour by mouse clicking the contour edges, change the value of time in the Input t text box, and click the Draw button to see the new shape and position of the material contour.
- To illustrate Kelvin's theorem through simple velocity fields,
- To illustrate the connection between vorticity and circulation through simple velocity fields.
