Explicit/implicit fluid structure staggered procedures with a structural predictor and fluid subcycling for 2D inviscid aeroelastic simulations. (English)
[J] Int. J. Numer. Methods Fluids 25, No.10, 1207-1226 (1997). ISSN 0271-2091; ISSN 1097-0363/e

The paper describes a coupling staggered procedure for the transient solution of coupled aeroelastic problems. To this end, dynamic meshes and finite volume schemes based on the ALE formulation of the Euler equations are employed, whereby moving grids are taken into account which becomes necessary since the fluid domain boundaries are time-dependent, in general. The presented scheme extends the partitioned procedures which have been elaborated for coupled linear one-dimensional problems to nonlinear two-dimensional Euler equations in the aeroelastic case. Thereby a novel staggered procedure with structural predictor is introduced. Two test cases, a transonic flow past an oscillating NACA 0012 airfoil and a supersonic flutter of a flat panel with finite aspect ratio, are investigated to show the performance and ability of the scheme.
