چکیده

Abstract. A new method for high-fidelity aeroelastic static analysis of composite laminated wings is proposed. The structural and the fluid-dynamic are coupled in a heterogeneous staggered process. Finite Element Method (FEM), Carrera Unified Formulation (CUF) Equivalent Plate Modelling (EPM) combined to model complex three-dimensional geometries bi-dimensional framework; Computational Fluid Dynamics (CFD) employed solve Navier-Stokes equations different turbulence models (i.e. Spalart-Allmaras) through SU2, an open-source software that implements C++ routines 3D fluid-dynamics analysis. Moving Least Square patch technique adopted manage fluid-structure interaction. use equivalent plate model, as opposite 1D often literature, shows competitive performances terms number degrees freedom. High-fidelity aerodynamics allows studying non-linear phenomena associated irregularities interaction, showing level accuracy low-fidelity methods such Vortex Lattice (VLM) Doublet (DLM) unable provide. Such advantages balanced by need elaborate iterative resolution problems, which leads higher computational costs.

4D geomechanical simulations for field development planning

3D and 4D geomechanical can be time-consuming to build and calibrate. However, once such a model is built, it is relative straightforward to use this model for various field development and management applications. In so doing, the return on the initial investment of time and effort in the creation of a 4D geomechanical model can be substantial. I present a case study where a 4D geomechanical m...
