A Generalized LinDistFlow Model for Power Flow Analysis [PDF]

2021 60th IEEE Conference on Decision and Control (CDC), 2021
This paper proposes a new linear power flow model for distribution system with accurate voltage magnitude estimates. The new model can be seen as a generalization of LinDistFlow model to multiphase distribution system with generic network topology (radial or meshed) around arbitrary linearization point.

Numerical analysis of cavitation shedding flow around a three-dimensional hydrofoil using an improved filter-based model [PDF]

, 2017
The cavitation shedding flow around a 3-D Clark-Y hydrofoil is simulated by using an improved filter-based model (FBM) and a mass transfer cavitation model with the consideration of the maximum density ratio effect between the liquid and the vapor.
