Analysis of high-order velocity moments in a strained channel flow
S. V. Poroseva, S. M. Murman
In the current study, model expressions for fifth-order velocity moments obtained from the truncated Gram-Charlier series expansions model for a turbulent flow field probability de…
Optimization of Survivability Analysis for Large-Scale Engineering Networks
S. V. Poroseva, P. A. Rikvold
Engineering networks fall into the category of large-scale networks with heterogeneous nodes such as sources and sinks. The survivability analysis of such networks requires the ana…
Modeling power grids
P. A. Rikvold, I. Abou Hamad, B. Israels +1
We present a method to construct random model power grids that closely match statistical properties of a real power grid. The model grids are more difficult to partition than a rea…
"Selfish" algorithm for optimizing the network survivability analysis
Svetlana V. Poroseva
In Nature, the primary goal of any network is to survive. This is less obvious for engineering networks (electric power, gas, water, transportation systems etc.) that are expected…
Floridian high-voltage power-grid network partitioning and cluster optimization using simulated annealing
Ibrahim Abou Hamad, Per Arne Rikvold, Svetlana V. Poroseva
Many partitioning methods may be used to partition a network into smaller clusters while minimizing the number of cuts needed. However, other considerations must also be taken into…
Spectral matrix methods for partitioning power grids: Applications to the Italian and Floridian high-voltage networks
Ibrahim Abou Hamad, Brett Israels, Per Arne Rikvold +1
Intentional islanding is used to limit cascading power failures by isolating highly connected "islands" with local generating capacity. To efficiently isolate an island, one should…
Validation of a new k-epsilon model with the pressure diffusion effects in separated flows
Svetlana V. Poroseva, Gianluca Iaccarino
The contribution of the "rapid" part of the pressure diffusion to the turbulent kinetic energy balance is analyzed, and a new model to describe its effect is suggested. A new trans…
Modeling the "rapid" part of the velocity/pressure-gradient correlation in inhomogeneous turbulent flows
Svetlana V. Poroseva
A new model for the "rapid" part of the velocity/pressure-gradient correlation in the Reynolds averaged Navier-Stokes equations is suggested. It is shown that in an inhomogeneous i…
