A comparative study of time-marching schemes for fluid-structure interactions

摘要：

　　Four types of partitioned time-marching schemes, namely the iterative staggered serial(ISS) scheme, the conventional serial staggered serial (CSS) scheme, the generalized serial staggered scheme (GSS), and the serial staggered scheme with fluid loads predictions (FPSS), are presented for accuracy comparisons of nonlinear fluid-structure interactions (FSI).A 2-DOF aeroelastic model for an airfoil is used as an example to illustrate the effects of different control parameters of the schemes.Some modifications are made to the schemes to improve the FSI simulation accuracy.The numerical results show that the GSS and FPSS are accurate and robust if the default parameters are adopted.Moreover, the accuracy of FPSS can be further improved by simply tuning the control parameters.
