TL;DR: In this paper, the conservation properties of the mass, momentum, and kinetic energy equations for incompressible flow are specified as analytical requirements for a proper set of discrete equations, and finite difference schemes for regular and staggered grid systems are checked for violations of the conservation requirements and a few important discrepancies are pointed out.

TL;DR: In this article, the Navier-Stokes equations are used to model the evolution of a turbulent mixing layer and turbulent channel flow in incompressible Newtonian fluids. And the results of simulations of homogeneous turbulence in uniform shear are presented graphically and discussed graphically.

TL;DR: Germano et al. as mentioned in this paper proposed a method for computing coefficients of subgrid-scale eddy viscosity models as a function of space and time, which can be applied to general inhomogeneous flows and does not suffer from the mathematical inconsistencies inherent in the previous formulation.

TL;DR: In this article, the Reynolds stresses and the dissipation rate of the turbulence kinetic energy are computed using direct simulation data of a turbulent channel flow using a closed-loop model, where the budget data reveal that all the terms in the budget become important close to the wall.

TL;DR: In this article, the authors explore concepts for active control of turbulent boundary layers leading to skin-friction reduction using the direct numerical simulation technique and show that significant drag reduction is achieved when the surface boundary condition is modified to suppress the dynamically significant coherent structures present in the wall region.
