Thermal Estimation and Thermal Design for Coupling Coils of 6.6 kW Wireless Electric Vehicle Charging System

open access: yesEnergies, 2022
Wireless electric vehicle charging technology is developing in the direction of high power levels. However, more generated heat brought by higher power will accelerate the system’s aging and can even lead to damage.

Characterization of Ductile Crack Propagation by Fractal Energy Dissipation Rate

open access: yesApplied Sciences, 2022
Because of its geometry dependence and loss of physical meaning, the incremental crack resistance curve cannot characterize ductile fractures with large crack extensions and plastic deformations.

An Experimental Study of Pile-Supported OWC-Type Breakwaters: Energy Extraction and Vortex-Induced Energy Loss

open access: yesEnergies, 2016
Integrating wave energy converters with breakwaters is a promising concept for wave energy utilization. On the basis of fulfilling the wave protection demands, pile-supported Oscillating Water Column (OWC)-type breakwaters can also meet the local needs ...

Thermo-optic noise in coated mirrors for high-precision optical measurements [PDF]

open access: yes, 2008
Thermal fluctuations in the coatings used to make high-reflectors are becoming significant noise sources in precision optical measurements and are particularly relevant to advanced gravitational wave detectors. There are two recognized sources of coating

Microscopic nanomechanical dissipation in gallium arsenide resonators [PDF]

open access: yes, 2018
We report on a systematic study of nanomechanical dissipation in high-frequency (approximatively 300 MHz) gallium arsenide optomechanical disk resonators, in conditions where clamping and fluidic losses are negligible.

The radial effective temperature distribution of steady-state, mass-losing accretion disks [PDF]

open access: yes, 1999
Mass loss appears to be a common phenomenon among disk-accreting astrophysical systems. An outflow emanating from an accretion disk can act as a sink for mass, angular momentum and energy and can therefore alter the dissipation rates and effective ...

Analysis of Temperature Field and Water Cooling of Outer Rotor In-Wheel Motor for Electric Vehicle

open access: yesIEEE Access, 2019
In view of the narrow installation space of high power density and high torque in-wheel motor, the heat existed the in-wheel motor is balanced by cooling water channel to ensure the heat dissipation of the high power density in-wheel motor. In this paper,

Engineering tunable local loss in a synthetic lattice of momentum states

open access: yesNew Journal of Physics, 2019
Dissipation can serve as a powerful resource for controlling the behavior of open quantum systems. Recently there has been a surge of interest in the influence of dissipative coupling on large quantum systems and, more specifically, how these processes ...
