Second-and fourth-order-accurate spatial discretization methods give rise to discretization errors which are larger than the corresponding subgrid terms in large eddy simulation of compressible shear layers in 2D, if the ratio between the filter width and the grid spacing is close to one. Even if an

Time-developing turbulent boundary layers over an isothermal flat plate at freestream Mach numbers of 0.3 and 0.7 are computed using an explicit finite-difference method on structured multi-block grids. The size of each block is adjusted depending on the dimension of the largest structures present l
In this article, large eddy simulation is used to simulate homogeneous shear ows. The spatial discretization is accomplished by the spectral collocation method and a third-order Runge-Kutta method is used to integrate the time-dependent terms. For the estimation of the subgrid-scale stress tensor, t
The methods used for the study of the impingement of a thermally inhomogeneous plane jet on a solid plate, using large-eddy simulation, are described. Innovative numerical methods have been introduced to produce the thermally inhomogeneous jet, to study the transmission of thermal fluctuations into
