In real-world fluid problems, boundary shape and motion are not simple in
general. e.g. insects flight by flapping wings, large deformation of free-surface motion, etc. In such cases, the global flow is coupled with the boundary motion (such as insects’ center-of-mass and free surface); Both should be considered simultaneously. The global flow structure itself sometimes has several time and spatial scales. Such hierarchical flow structures are also interacting with flow structures in other scales. I am interested in such structures and interactions.
