Summary

Fluid-structure coupling problem is one of the most significant engineering problems in many applications, e.g., Aviation, navigation, etc. The biggest challenge is computational modelling, especially fast numerical modelling. When considering fluid-structure coupling modelling, it is necessary to simulate unsteady aerodynamic forces, structural transient deformation, vibration and etc. Such research often requires a large number of simulations and experiments, including complicated coupling experiments. Artificial intelligence methods can greatly improve the modelling speed of complex engineering problems. If it is combined with studies of fluid-structure coupling problems, it can enhance the research efficiency of such problems. Therefore, modelling methods, simulation methods, optimization methods, etc, for fluid-structure coupling problems are urgently demanded in engineering research.


This Special Issue aimed to present advanced computational modelling methods from representative Mathematical, simulated, and experimental methods. It can include, but not be limited to, engineering simulation, numerical modelling, intelligent algorithms for aerodynamics, structural dynamics, and fluid-structure coupling problems.

Suggested themes are listed below:
· Fast modelling methods via machine learning, artificial intelligence, etc
· Fluid-structure coupling modelling and simulation
· Aeroelastic modelling and simulation
· Dynamic optimization related to fluid-structure coupling
· Thermal dynamic via structure characteristic

    Abstract This study presents an implicit multiphysics coupling method integrating Computational Fluid Dynamics (CFD), the Multiphase Particle-in-Cell (MPPIC) model, and the Finite Element Method (FEM), implemented with OpenFOAM, CalculiX, and preCICE to simulate fluid-particle-structure interactions with large deformations. Mesh motion in the fluid field is handled using the radial basis function (RBF) method. The particle phase is modeled by MPPIC, where fluid-particle interaction is described through momentum exchange, and inter-particle collisions are characterized by collision stress. The structural field is solved by nonlinear FEM to capture large deformations induced by geometric nonlinearity. Coupling among fields is More >
