Coupling Stability and Multi‐Frequency Transient Characteristics of a Variable Speed Pumped Storage Power Station Under Generating Mode

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Coupling stability and multi‐frequency transient characteristics of variable speed pumped storage power station (VSPSPS) under generating mode are main topics of this paper. Firstly, the overall model of VSPSPS is established and the coupling stability analysis of VSPSPS is carried out. Then, multi‐frequency transient characteristics of VSPSPS

A High‐Order Hybrid‐Spectral Incompressible Navier–Stokes Model for Non‐Linear Water Waves

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 97, Issue 6, Page 1009-1021, June 2025.
We present a high‐order accurate CFD model for simulating nonlinear water waves using the incompressible Navier–Stokes equations. The model employs a combined Chebyshev–Fourier basis for efficient spatial discretization, and a low‐storage fourth‐order Runge–Kutta method for temporal integration. A Poisson pressure problem is solved using a geometric p$$

Vortex Panel Method in Axisymmetric Cylindrical Coordinates: Inviscid Formulation

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
An efficient numerical method for solving potential flows past axisymmetric objects is proposed. Green's function corresponding to the governing equation is derived and analytically verified. Using the derived Green's function, the vortex panel method is constructed, and its validity was confirmed through comparison with results obtained by other ...

Measuring the Impact of Transition Risk on Financial Markets: A Joint VaR‐ES Approach

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Based on a joint quantile and expected shortfall semiparametric methodology, we propose a novel approach to forecasting market risk conditioned to transition risk exposure. This method allows us to forecast two climate‐related financial risk measures called CoClimateVaR$$ CoClimateVaR $$ and CoClimateES$$ CoClimateES $$, being jointly ...
