Hydrodynamic and Magnetohydrodynamic Turbulent Flows

TUrbulence modeling encounters mixed evaluation concerning its impor­ tance. In engineering flow, the Reynolds number is often very high, and the direct numerical simulation (DNS) based on the resolution of all spatial scales in a flow is beyond the capability of a computer available at present and in the foreseeable near future. The spatial scale of energetic parts of a turbulent flow is much lar...
