Full-Space Approach to Aerodynamic Shape Optimization
Doug Shi-Dong, Siva Nadarajah
Aerodynamic shape optimization (ASO) involves finding an optimal surface while constraining a set of nonlinear partial differential equations (PDE). The conventional approaches use…
Numerical Dissipation Based Error Estimators and Grid Adaptation for Large Eddy Simulation
Yao Jiang, Siva Nadarajah
Grid adaptation for implicit Large Eddy Simulation (LES) is a non-trivial challenge due to the inherent coupling of the modeling and numerical errors. An attempt to address the cha…
A robust quasi-optimal test norm for a DPG discretization of the convection-diffusion equation
Stephen Metcalfe, Siva Nadarajah
In this work, we propose a new quasi-optimal test norm for a discontinuous Petrov-Galerkin (DPG) discretization of the ultra-weak formulation of the convection-diffusion equation.…
An asynchronous incomplete block LU preconditioner for computational fluid dynamics on unstructured grids
Aditya Kashi, Siva Nadarajah
We present a study of the effectiveness of asynchronous incomplete LU factorization preconditioners for the time-implicit solution of compressible flow problems while exploiting th…
On the Geometric Conservation Law for the Non Linear Frequency Domain and Time-Spectral Methods
Marc Benoit, Siva Nadarajah
The aim of this paper is to present and validate two new procedures to enforce the Geometric Conservation Law (GCL) on a moving grid for an Arbitrary Lagrangian Eulerian (ALE) form…
On the verification of CFD solvers of all orders of accuracy on curved wall-bounded domains and for realistic RANS flows
Farshad Navah, Siva Nadarajah
This paper aims at extending the code verification methodology to high-order accurate scheme implementations on curved wall-bounded domains as well as for realistic turbulent flows…
