5. Concluding Remarks

The time evolution of an unstable elliptical vortex patch was analyzed using a contour dynamics model.

Calculations of streamfunctions, passive contour advections, and finite-time Lyapunov exponents revealed the deformation mechanism of the vortex patch and gave visualized recognitions and a quantitative measure of the fluid mixing.
