Vorticity dynamics and control of self-propelled flying of a three-dimensional bird

摘要：

　　Birds are propelled and lifted by wings flapping and rotating motion.In our past study we found that adjusting the flapping period,flapping amplitude can achieve better flying,the bird can fly faster forward when the flapping period is shorter and fly faster upward when the flapping amplitude is larger.In this study,the rotation amplitude and rotation time interval of wings were studied,we found that the bird can also fly faster forward or upward with appropriate rotation amplitude and rotation time interval.In this study,the numerical simulation of three-dimensional bionic birds self-propelled flying in a viscous flow and a three-dimensional computational fluid dynamics package are used,and the package includes the immersed boundary method,the volume of fluid method,the adaptive multi-grid finite volume method,and the swimming and flying control strategy.
