Generalised Mixing-Plane Method for Compressible Reacting-Mixture Flows in Steady Multiphysics Turbomachinery Simulations
Yifeng Wang, Lin Shi, Fenglai Huang +3
The mixing-plane method plays a pivotal role in steady simulations of multiple turbomachinery components. With advances in computational power, a whole-engine gas turbine simulatio…
A subcell-refined entropy-residual-driven limiting strategy for high-order discontinuous Galerkin methods
Geng Liang, Rui Wang, Junjie Wang +3
Fine-grained, subcell-level dissipation control is essential for achieving robust high-order discontinuous Galerkin (DG) simulations of nonlinear hyperbolic systems in under-resolv…
Identifying sensitivity-dominant parameters via active subspaces in reduced-order modeling of fluid dynamics
Dewu Yang, Rui Wang, Pengyu Lai +3
Reduced-order models (ROMs) are widely employed to describe complex system dynamics when simulations with full-order models (FOMs) are computationally prohibitive. This study prese…
From Complex Dynamics to DynFormer: Rethinking Transformers for PDEs
Pengyu Lai, Yixiao Chen, Dewu Yang +3
Partial differential equations (PDEs) are fundamental for modeling complex physical systems, yet classical numerical solvers face prohibitive computational costs in high-dimensiona…
