Research Topics

Fish swimming fluid mechanics
To understand the mechanics of fish swimming, we need to know the forces exerted by the fluid and how these forces affect the motion of the fish. To elucidate the hydrodynamic mechanisms behind the highly non-linear and complicated nature in fish swimming hydrodynamics, I have developed an integrated three-dimensional (3D)computational approach of hydrodynamics and body dynamics that couples the Navier-Stokes (NS) equations with the equations of undulating body motion. By using both experimental and computational approaches, hidden relationships between fluid dynamic phenomenon and fish swimming skills are reveled.
Fish swimming optimization Strategy
By pragmatically exploring how body wave frequency and amplitude affect swimming performance and comparing with experimental observation. My research indicate that fish swimming strategy is NOT optimized for highest propulsive efficiency (thrust×speed÷ power), instead, fish adjust their body kinematics to optimize towards minimum transport cost (power÷speed) at particular speed. This novel philosophy may redirect all future researches on fish swimming and swimming robot.
