Acoustic power measurements of oscillating flames [PDF]

open access: yes, 1981
The acoustic power of an oscillating flame is measured. A turbulent premixed propane/air flame is situated near a pressure antinode of a standing wave in a laboratory combustion chamber. This standing wave is generated by a piston.

Optimal Design and Performance Analysis of a Hybrid System Combining a Semi-Submersible Wind Platform and Point Absorbers

open access: yesJournal of Marine Science and Engineering, 2023
Integrating point absorber wave energy converters (PAWECs) and an offshore floating wind platform provide a cost-effective way of joint wind and wave energy exploitation. However, the coupled dynamics of the complicated hybrid system and its influence on

The cosmological gravitational wave background from primordial density perturbations [PDF]

open access: yes, 2006
We discuss the gravitational wave background generated by primordial density perturbations evolving during the radiation era. At second-order in a perturbative expansion, density fluctuations produce gravitational waves. We calculate the power spectra of

Critical wave-packet dynamics in the power-law bond disordered Anderson Model [PDF]

open access: yes, 2005
We investigate the wave-packet dynamics of the power-law bond disordered one-dimensional Anderson model with hopping amplitudes decreasing as $H_{nm}\propto |n-m|^{-\alpha}$. We consider the critical case ($\alpha=1$).

On the Optimal Pole Width for Direct Drive Linear Wave Power Generators Using Ferrite Magnets

open access: yesEnergies, 2018
In this work, ferrite magnet linear generators for wave power applications are considered. These machines operate at unusually low speeds, around and even below 1 m/s, at which the optimal geometry differs from standard machines, since the copper loss ...

Wave energy potential along the Atlantic coast of Morocco [PDF]

open access: yes, 2016
This study analyses the wave energy resource along the Atlantic coast of Morocco using a 44-year series of data obtained from numerical modeling (hindcasting). The spatial distribution of wave power is analyzed using data from 23 points along that coast.

Direct numerical simulations of capillary wave turbulence [PDF]

open access: yes, 2014
This work presents Direct Numerical Simulations of capillary wave turbulence solving the full 3D Navier Stokes equations of a two-phase flow. When the interface is locally forced at large scales, a statistical stationary state appears after few forcing ...

Assessment of Extreme and Metocean Conditions in the Swedish Exclusive Economic Zone for Wave Energy

open access: yesAtmosphere, 2020
Here, accessibility to near-shore and offshore marine sites is evaluated based on wave and ice conditions. High-resolution third-generation wave model results are used to examine the operation and maintenance conditions for renewable energy sources with ...
