With the introduction of massive renewable energy sources and storage devices, traditional process grid operation must be improved in order to safe, reliable, fast responsive cost efficient, this regard power flow solvers are indispensable. In paper, we introduce an Interior Point-based (IP) Multi-Period AC Optimal Power Flow (MPOPF) solver for integration Stationary Energy Storage Systems (SES...

We analyze the dynamics of problem-solving in a framework which captures two key features of that activity. The first feature is that problem-solving is a social game where a number of problem-solvers interact, rely on other agents to tackle parts of a problem, and regularly communicate the outcomes of their investigations. The second feature is that problem-solving requires a careful control o...

This paper concerns the Time-Domain Full Waveform Inversion (FWI) for dispersive and dissipative poroelastic materials. The forward problem is an initial boundary value (IBVP) of equations with a memory term; FWI formulated as minimization least-square misfit function constraint. In this paper, we derive adjoint problem, whose solution can be applied to computed direction steepest descent in it...

This document describes the SAT solver “CCAglucose2015”, which first empoys a preprocessor CP3, and then calls a hybrid solver combining a local search solver CCAnr and a complete solver glucose.

A new multi-state Harten–Lax–van Leer (HLL) approximate Riemann solver for the ideal magnetohydrodynamic (MHD) equations is developed based on the assumption that the normal velocity is constant over the Riemann fan. This assumption is same as that used in the HLLC (‘‘C’’ denotes Contact) approximate Riemann solver for the Euler equations. From the assumption, it is naturally derived that the R...

This manuscript presents an updated open-source version of the Hypersonics Task-based Research (HTR) solver. The solver, whose main features are presented in Di Renzo et al. (2020) [9] and & Pirozzoli (2021) [10], is designed for direct numerical simulation reacting flows at high Reynolds numbers. new extends applications HTR solver to turbulent combustion presence external electric fields. In ...

Aeroelastic Computational Fluid Dynamics simulations have traditionally been associated to a high computational cost, making them prohibitive in initial phase of the design. Analytic models, which may not be accurate for nonlinear aerodynamics, utilized order size those structures. Recently, some authors proposed use artificial neural networks reduce error prediction aerodynamic coefficients bl...

In this paper, we are interested in taking into account uncertainties for keff computations neutronics. More generally, the material of paper can be applied to propagate eigenvalue/eigenvector linear Boltzmann equation. [1], [2], an intrusive MC solver gPC based reduced model instationary equation has been put forward. The MC-gPC presents interesting characteristics (mainly a better efficiency ...
