Parallel DNS using a compressible turbulent channel flow benchmark
Parallel DNS using a compressible turbulent channel flow benchmark
In recent years, the increased use of off-the-shelf components and the large-scale adoption of parallel computing have led to a dramatic reduction in the costs associated with high-performance computing. This has enabled increased usage of compute-intensive methods, such as Direct Numerical Simulation (DNS), for the simulation of turbulent flows. We introduce a sophisticated DNS code that incorporates a number of advanced features:high-order central differencing; a shock-preserving advection scheme from the total variation diminishing (TVD) family; entropy splitting of the Euler terms and the associated stable boundary treatment.

Abstract
In recent years, the increased use of off-the-shelf components and the large-scale adoption of parallel computing have led to a dramatic reduction in the costs associated with high-performance computing. This has enabled increased usage of compute-intensive methods, such as Direct Numerical Simulation (DNS), for the simulation of turbulent flows. We introduce a sophisticated DNS code that incorporates a number of advanced features:high-order central differencing; a shock-preserving advection scheme from the total variation diminishing (TVD) family; entropy splitting of the Euler terms and the associated stable boundary treatment.
