چکیده
In this paper, we survey numerical methods used in aeroelasticity simulations. These methods are based on two-dimensional Euler equations. However, they are quite general. First, we consider uid dynamics numerical methods, which are also used to solve moving boundaries problems. Fixed computational domain methods (possibly with multiple moving frames of reference) are introduced. Arbitrary Lagrangian-Eulerian and dynamic meshes formulations are also presented. Second, we discuss the most used algorithm for interaction simulation in aeroelastic computations. Finally, we present numerical methods for structural dynamics. Dans ce rapport, nous pr esentons un eventail de m ethodes num eriques pour l' a ero elasticit e. Ces m ethodes s'adaptent a de nombreux types d' equations. Elles sont ici expos ees sur la base des equations d'Euler bi-dimensionnelles. Dans un premier temps, nous consid erons les m ethodes utilis ees pour la partie uide, qui permettent aussi de r esoudre des probl emes a parois mobiles. Nous pr esentons des m ethodes a domaine de calcul xe, avec d' eventuels rep eres mobiles, ainsi que les formulations de type ALE ou maillages dynamiques. Ensuite, nous analysons l'algorithme g en eralement utilis e pour simuler l'interaction. Ennn, nous pr esentons quelques m ethodes num eriques pour simuler les mouvements des structures.

Stabilization of Linear Flow Solver for Turbomachinery Aeroelasticity Using Recursive Projection Method
The linear analysis of turbomachinery aeroelasticity relies on the assumption of small level of unsteadiness and requires the solution of both the nonlinear steady and the linear unsteady flow equations. The objective of the analysis is to compute a complex flow solution that represents the amplitude and phase of the unsteady flow perturbation for the frequency of unsteadiness of interest. The ...
متن کاملLattice numerical simulations of hydraulic fractures interacting with oblique natural interfaces
The hydraulic fracturing propagation is strongly influenced by the existence of natural fractures. This is a very important factor in hydraulic fracturing operations in unconventional reservoirs. Various studies have been done to consider the effect of different parameters such as stress anisotropy, toughness, angle of approach and fluid properties on interaction mechanisms including crossing, ...

Within the basic framework of an existing anisotropic thin-walled beam model, a cou-ple of non-classical effects are further incorporated and the model thereby developed isvalidated. Three types of lay-up configurations, namely, the cross-ply, circumferentiallyuniform stiffness (CUS), and circumferentially asymmetric stiffness (CAS) are investi-gated. The solution methodology is...
متن کاملA New Multivariate Interpolation Method for Large-scale Spatial Coupling Problems in Aeroelasticity
In this contribution, a new and efficient multivariate interpolation scheme is presented which is designed for large-scale coupling problems in the field of numerical aeroelasticity. The scheme is based upon a local application of radial basis functions (RBFs). The new method is tested in several numerical aeroelastic computations, and compared to a competing, widely used global approach. The i...
متن کاملHydraulic fracture propagation: analytical solutions versus Lattice simulations
In this work, we used a grain-based numerical model based on the concept of lattice. The modelling was done to simulate the lab experiments carried out on the mortar samples. Also the analytical solutions corresponding to the viscosity-dominated regime were used to estimate the fracture length and width, and the results obtained were compared with the numerical simulations. As the analytical so...
