We present a method for computing fluid–structure interaction problems for multi-body
systems. The fluid flow equations are solved using a fractional-step method with the …

Large-amplitude flow disturbances, or gusts, can drastically alter the aerodynamic forces on
an airfoil and are regularly investigated through wind tunnel (or water tunnel) experiments …

Large amplitude flow disturbances and gusts can drastically alter the aerodynamic forces on
airfoils or structures. The modeling and control of the aerodynamic response of the flow …
