In a previous post I introduced the concept of boundary layer separation and how aquatic animals actively or passively morph their skins to delay this phenomenon. As a brief recap, when flow over a surface encounters an adverse pressure gradient (i.e. the fluid pressure increases in […]

Bio-mimetic Drag Reduction – Part 3: Morphing

On April 5, 2012 · In Aerodynamics, Bio-mimicry

In the previous two posts of this blog series I introduced the different sensing mechanism that aquatic animals possess to create spatial images of the largely turbulent flow fields around them. Flow sensing has been shown to […]

Bio-mimetic Drag Reduction – Part 2: Aero- and Hydrodynamics

On March 31, 2012 · In Aerodynamics, Bio-mimicry

Part 1 of this blog series outlined the different sensing mechanisms that aquatic animals possess to create spatial images of the flow fields around them. In summary fish were found to possess a network of mechanosensors distributed over their bodies called the lateral line. The lateral line […]

Bio-mimetic Drag Reduction – Part 1: Sensing

On March 27, 2012 · In Bio-mimicry

Fish have a remarkable ability to sense the flow conditions around their bodies and subsequently manipulate their swimming behaviour to achieve efficient locomotion [1 – 2]. It has been observed that dolphins and sharks use a network of mechanosensors on their skin to create a spatial image of the flow around them and […]
