Energy-Saving Strategies of Axial Flow Fans for Direct Dry Cooling System
Energies, 2021 The operating conditions of axial flow fans are closely related to the thermo-flow characteristics of the mechanical draft direct dry cooling system. Moreover, the uneven distribution of cooling air driven by axial flow fans may lead to the deterioration

Insights into the Energy Transfers in Hydrodynamic Turbulence Using Field-theoretic Tools [PDF]
arXiv, 2023 Turbulent flows exhibit intriguing energy transfers. In this paper, we compute the renormalized viscosities, mode-to-mode energy transfers, energy fluxes, and shell-to-shell energy transfers for the two-dimensional (2D) and three-dimensional (3D) hydrodynamic turbulence (HDT) using field-theoretic methods.

Radiative and Non-Radiative Exciton Energy Transfer in Monolayers of Two-Dimensional Transition Metal Dichalcogenides [PDF]
Phys. Rev. B 93, 155422 (2016), 2016 We present results on the rates of interlayer energy transfer between excitons in two-dimensional transition metal dichalcogenides (TMDs). We consider both radiative (mediated by real photons) and non-radiative (mediated by virtual photons) mechanisms of energy transfer using a unified Green's function approach that takes into account modification of ...

Förster energy transfer between neighbouring chromophores in C-phycocyanin trimers [PDF]
, 1993 The excitation-energy transfer in C-phycocyanin (C-PC) trimers and monomers isolated from phycobilisomes of Mastigocladus laminosus has been studied by polarization femtosecond laser spectroscopy. Excitation with 70-fs pulses at 615 nm gave rise to a 500-

Vibronic Resonance Along Effective Modes Mediates Selective Energy Transfer in Excitonically Coupled Aggregates [PDF]
, 2022 We recently proposed effective normal modes for excitonically coupled aggregates which exactly transform the energy transfer Hamiltonian into a sum of one-dimensional Hamiltonians along the effective normal modes. Identifying physically meaningful vibrational motions which maximally promote vibronic mixing suggested an interesting possibility of ...

The optical control of electronic energy transfer through single and dual auxiliary beams [PDF]
, 2008 The electronic transfer of energy from a donor particle to an acceptor is a mechanism that plays a key role in a wide range of optical and photophysical phenomena. The ability to exert control on this transfer is of immense importance.
