Robust Power Flow and Three-Phase Power Flow Analyses [PDF]
IEEE Transactions on Power Systems, 2019 Robust simulation is essential for reliable operation and planning of transmission and distribution power grids. At present, disparate methods exist for steady-state analysis of the transmission (power flow) and distribution power grid (three-phase power flow).

Numerical simulation of turbulent duct flows with constant power input [PDF]
, 2014 The numerical simulation of a flow through a duct requires an externally specified forcing that makes the fluid flow against viscous friction. To this aim, it is customary to enforce a constant value for either the flow rate (CFR) or the pressure ...

Graphical Models for Optimal Power Flow [PDF]
, 2016 Optimal power flow (OPF) is the central optimization problem in electric power grids. Although solved routinely in the course of power grid operations, it is known to be strongly NP-hard in general, and weakly NP-hard over tree networks.

Numerical analysis of aerodynamic lubricated double-decked protuberant foil thrust bearing
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2019 Double-decked protuberant foil bearing is a type of foil bearing that uses two stacking-up layers of protuberant foils as supporting structure. In preliminary experiments, wear failure of foil thrust bearing occurs occasionally due to excessive axial ...
