Numerical investigation of passive and active flapping in fish propulsion
Final Report Abstract
Although the project did not fulfill the original objective totally, we still achieved an very important scientific advance, e.g. the unified modeling and simulation tool for fishing swimming. This tool has also potential to cope more general engineering problems involving fluid structure interactions. We really have faced a surprise in the course of the project, that is, the originally proposed coupling model is not able to handling the complex dynamical system of fish swimming. At last, we did not have enough time to investigate the passive and active flapping of the fish swimming model. However, we expected that this can be done at once we have successfully applied the second funding period.
