Chapter 4
High Reynolds Number Flows
Abstract
This chapter is about problems that really need High Performance Computing (HPC) to run. Twenty-first century computational flow dynamics is about Direct Numerical Simulation (DNS) and Large Eddy Simulation (LES) and almost all real-world flows are turbulent in nature; therefore, to predict flow physics accurately, computer algorithms must be capable of fully resolving all structures to the Kolmogorov scale. This chapter will discuss why DNS and LES are important in turbulence and why HPC is the answer to these large problems.
