Study on Two-dimensional Wing Flutter Analysis by a High-order Flux Reconstruction Method

摘要：

　　Wing flutter analyses are carried out by a newly developed flow solution method using high-order flux reconstruction approach.The significance steps to be achieved are the moving boundary/moving grid technique in high-Reynolds number flows.The k-ω turbulence model is implemented for the objectives.The method is first validated by a forced oscillation and then fluid-structure coupled flutter simulations are carried out in subsonic flows.The predicted flutter boundary well agreed with previous numerical studies.It is found that 3rd-and 4th-order spatial accuracy produces almost the identical results in the presented cases,while the viscous effects the flutter boundary.Preliminary results in transonic flow with shock waves are also included.
