Ocean waves, environmental fluid mechanics and coastal dynamics




Research Interests

Dr. Yu’s primary interests are in theoretical fluid dynamics and applied mechanics, with emphases on wave mechanics, hydrodynamic instabilities, coastal hydrodynamics and seabed mechanics. Current research focuses include:

  • waves over arbitrary periodic topographies and Bragg resonances;
  • terrain-following boundary layer flows and ripple induced flows;
  • wave-current-sediment morphology interactions in nearshore oceans;
  • Kelvin-Helmholtz instability in vegetated wetlands;
  • wave-structure interactions and ocean renewable energy;
  • Lagrangian ocean data assimilation;
  • rectification of oscillating motions, peristaltic transport and micro-pumping.

Interests in Applied Mathematics include: conformal mapping, Floquet theory, multi-scale perturbation techniques and homogenization.
