Characteristics of Energy Dissipation Rate Observed from the High-Frequency Sonic Anemometer at Boseong, South Korea

open access: yesAtmosphere, 2021
The characteristics of low-level turbulence at Boseong, located on the southern coast of South Korea, were investigated in terms of eddy dissipation rate (EDR) using 1-year (2018) of wind data obtained from the Boseong Meteorological Observatory (BMO), a

Entropy-Assisted Computing of Low-Dissipative Systems [PDF]

open access: yesEntropy, 2015
Entropy feedback is reviewed and highlighted as the guiding principle to reach extremely low dissipation. This principle is illustrated through turbulent flow simulations using the entropic lattice Boltzmann scheme.

Lagrangian measurements of turbulent dissipation over a shallow tidal flat from pulse coherent Acoustic Doppler Profilers [PDF]

open access: yes, 2012
We present high resolution (25 mm spatial, 8 Hz temporal) profiles of velocity measured over a shallow tidal flat using pulse-coherent Acoustic Doppler Profilers mounted on surface drifters.

Dissipation Assisted Frequency Comb and Chaos Generation in the Optomechanics

open access: yesIEEE Photonics Journal, 2022
Dispersion and dissipation are the key parameters of the optical components. Generally, dissipation is an unfavorable factor. In this article, we designed a dispersion-dissipation hybird coupling optomechanical cavity and achieved dissipation-assisted ...

Carnot-Like Heat Engines Versus Low-Dissipation Models

open access: yesEntropy, 2017
In this paper, a comparison between two well-known finite time heat engine models is presented: the Carnot-like heat engine based on specific heat transfer laws between the cyclic system and the external heat baths and the Low-Dissipation model where ...

Numerical investigation of the turbulence characteristics and energy dissipation mechanism of baffle drop shafts

open access: yesWater Science and Technology, 2021
The baffle drop shaft is widely used in deep tunnel drainage systems due to its fine applicability and high energy dissipation. To fully study the turbulence characteristics and energy dissipation mechanism of baffle drop shafts, a 1:25 scale physical ...

Low-dissipation central-upwind schemes for compressible multifluids

open access: yesJournal of Computational Physics, 2023
We introduce second-order low-dissipation (LD) path-conservative central-upwind (PCCU) schemes for the one- (1-D) and two-dimensional (2-D) multifluid systems, whose components are assumed to be immiscible and separated by material interfaces. The proposed LD PCCU schemes are derived within the flux globalization based PCCU framework and they employ ...
