TL;DR: This Review will describe recent theoretical advances including treatment of electronic decoherence in surface-hopping methods, the role of solvent effects, trivial unavoided crossings, analysis of data based on transition densities, and efficient computational implementations of these numerical methods.
Journal ArticleDOI
Parametric studies and optimisation of pumped thermal electricity storage
TL;DR: In this paper, a thermodynamic analysis is presented based on traditional cycle calculations coupled with a Schumann-style model of the packed beds, and results of an optimisation study are then given in the form of trade-off surfaces for roundtrip efficiency, energy density and power density.
Journal ArticleDOI
Classical nucleation theory and its application to condensing steam flow calculations
TL;DR: In this paper, the classical theory of homogeneous nucleation of water droplets from supersaturated vapour and its application in predicting condensation in steam nozzles is discussed.
Journal ArticleDOI
Thermodynamic analysis of pumped thermal electricity storage
TL;DR: In this paper, the authors studied the thermodynamic aspects of PTES, including energy and power density, and the various sources of irreversibility and their impact on round-trip efficiency.
Journal ArticleDOI
Experimental Validation of Condensing Flow Theory for a Stationary Cascade of Steam Turbine Blades
TL;DR: In this paper, a detailed experimental and theoretical study of non-equilibrium condensing steam flow in a stationary cascade of turbine blades operating transonically is described, and the thermodynamic loss due to irreversible condensation directly from experimental measurements.
