报告摘要：

The biomimetic engineering is a scientific discipline of implementing nature-inspired ideas to engineering systems for their performance enhancement. Based on the premise that the features of living organisms are potentially optimal solutions for their survival and reproduction, the flow-control society has shown much interest in applying plant- and animal-based solutions to the development of novel concepts or techniques for successful flow control. In this talk, we show that some morphological features of living creatures such as the ridges on the leatherback sea turtle, grooves on the scallop, tubercles on the flipper of humpback whale, alula on the feather of the magpie, etc., are not aligned in the streamwise direction, generate strong streamwise vortices, and control flow around or behind them, resulting in drag reduction and/or lift enhancement. Examples of applying these morphological features to engineering devices will be also introduced.
