A p-multigrid spectral difference method for two-dimensional unsteady incompressible Navier–Stokes equations
Spectral difference method Artifi cial compressibility method Dual time stepping p-Multigrid
2015/7/3
This paper presents the development of a 2D high-order solver with spectral difference method for unsteady incompressible Navier–Stokes equations accelerated by a p-multigrid method. This solver is de...
A Systematic Study on the Impact of Dimensionality for a Two-Dimensional Aerodynamic Optimization Model Problem
Systematic Study Impact Dimensionality Two-Dimensional Aerodynamic Optimization Model Problem
2015/7/3
A model problem, based on the NACA0012 airfoil, is studied. The thickness distribution of the symmetric NACA0012 airfoil is optimally approximated with a 4th-order Bezier curve. This best-fit ap...
In Pursuit of Grid Convergence for Two-Dimensional Euler Solutions
Grid Convergence Two-Dimensional Euler Solutions
2015/7/3
Grid-convergence trends of two-dimensional Euler solutions are investigated. The airfoil geometry under study is based on the NACA0012 equation. However, unlike the NACA0012 airfoil, which has a blunt...
A Two-Dimensional Multigrid-Driven Navier-Stokes Solver for Multiprocessor Architectures
Two-Dimensional Multigrid-Driven Navier-Stokes Solver Multiprocessor Architectures
2015/7/1
A two-dimensional unsteady Navier-Stokes solver has been parallelized using a domain decomposition approach and the PVM message passing library. Several options for the treatment of multigrid and impl...
Suppression of vortex-induced forces on a two-dimensional circular cylinder by a short and thin splitter plate interference
circular cylinder splitter plate interference
2015/6/23
This paper briefly reviews bluff body aerodynamics and focuses mainly on
the use of short and thin splitter plates to interfere with the vortex wakes and
suppress vortex-induced forces (VIF). The ...
