Robustness of Flow Phenomena in a Spatially Developing Turbulent Mixing Layer simulation using inflow perturbations derived from linear stability theory. Furthermore a resolution study is done. Robustness of flow phenomena is studied by applying an alternative inflow forcing which uses random perturbations. The results are discussed and compared with data from physical exper

Direct Numerical Simulation of Transitions Toward Turbulence in Complex Channel Flowsry instability of complex channel flows. The Navier-Stokes equations for incompressible flow are solved in generalized curvilinear coordinates so that channel flows may be investigated in which the walls of the channel are both curved and wavy. The channel geometry and the flow solution are assumed

Implementation of an SGS Model in a B-Spline Spectral Method and LES of a Turbulent Axial Vortexed in physical space and then expressed in terms of a b-spline expansion. The inner product operation on this term leads to four integrals involving double products of b-splines. Two of these already are part of the formulation of the other terms in the weak form of the Navier-Stokes equation and ar

Assessment of the Generalized Scale-Similarity Model in Homogeneous Turbulence Subjected to Rotationed via the convolution integral of . with the filter function, .. In the present study, the spherically symmetric Gaussian filter function was used, in which the characteristic filter width, ., was set equal to 2Δ. Δ is the grid interval for the LES mesh. We consider the flow which is homogeneous in

Direct Numerical Simulation of Boundary-Layer Receptivity for Subsonic Flow Around Airfoileralized curvilinear coordinates are solved by LU-SGS implicit scheme, which requires no tridiagonal inversion and is capable of being completely vectorized and parallelized. A fourth-order centered compact scheme is used for spatial derivatives and second-order Euler Backward scheme is applied for
