Abstract
Many geophysical, environmental, biological, and engineering fluid flows involve turbulence interacting with a wavy surface. Examples include atmospheric and oceanic flows near the ocean surface and locomotion of swimmers with undulatory body motions. Compared with boundary-layer flows at flat surfaces, the kinematic constraints and dynamic distortion of wavy boundaries introduce new, complex flow features. In this talk, some of our recent developments in numerical capabilities for water waves and turbulent flows in wave environments will be introduced. The turbulent flows above and below the water surface waves will be illustrated, followed by theoretical analyses and modeling.
