Combined Feature-Driven Richardson-Based Adaptive Mesh Refinement for Unsteady Vortical Flows
Combined Feature-Driven Richardson-Based Adaptive Mesh Unsteady Vortical Flows
2015/7/3
An adaptive mesh refinement strategy that couples feature detection with local error estimation is presented. The strategyfirst selects vortical regions for refinement using feature ...

The history of computational fluid dynamics (CFD), especially as driven by the requirements of transonic flow prediction, has been largely coincident with the history of these Symposia. Th...
An Implicit-Explicit Hybrid Scheme for Calculating Complex Unsteady Flows
Implicit-Explicit Hybrid Scheme Calculating Complex Unsteady Flows
2015/7/2
In current practice, unsteady flow simulations for turbomachinery are performed using a dual-time-stepping scheme. This work is motivated by the need to solve the time accurate Navier-Stokes equ...
