Sea surface temperature control on the distribution of far-traveled Southern Ocean ice-rafted detritus during the Pliocene [PDF]

Paleoceanography, 2014
The flux and provenance of ice-rafted detritus (IRD) deposited in the Southern Ocean can reveal information about the past instability of Antarctica's ice sheets during different climatic conditions. Here we present a Pliocene IRD provenance record based on the Ar/Ar ages of ice-rafted hornblende grains from Ocean Drilling Program Site 1165, located ...

Using a side-branched volume to tune the acoustic field in a looped-tube travelling-wave thermoacoustic engine with a RC load [PDF]

, 2017
Travelling-wave thermoacoustic engine utilises a compact acoustic network to obtain a right time-phasing between the acoustic velocity and pressure oscillations within the regenerator to force gas parcels to experience a Stirling-like thermodynamic cycle.

Analytical Expression of the Beam-Plasma Particles Distribution Function Effect on the Electromagnetic Instability Growth Rate in Strongly Coupled Plasmas [PDF]

Iranian Journal of Astronomy and Astrophysics
The beam-plasma particles distribution function is one of the parameters which plays an important role in the energy-traveling mechanism of the relativistic electrons generated by the laser-plasma interaction in the Inertial Confinement Fusion Plasma ...

Response of the American equatorial ionization anomaly to 2016 Arctic sudden stratospheric warming events

Frontiers in Astronomy and Space Sciences, 2022
Apart from the rapid ionospheric response to geomagnetic forcing originating from the Sun during extreme space weather events, forcing from the lower atmosphere below still exerts a significant influence on the ionosphere during quiet-time conditions ...

THERMAL RATCHETTING ANALYSIS OF CYLINDERS SUBJECTED TO AXIAL TRAVELLING OF TEMPERATURE DISTRIBUTION

Journal of the Society of Materials Science, Japan, 1997
The paper deals with estimation of thermal ratchetting strain in cylinders subjected to short axial travelling of temperature distribution. The estimation is made by considering partly pressurized cylinders as a model. It is assumed that the pressurized region, which is taken to occupy the temperature travel region, is ruled by the deformation theory ...

Study of a Square Single-Phase Natural Circulation Loop Using the Lattice Boltzmann Method

Applied Mechanics, 2023
Natural circulation loops are thermohydraulic circuits used to transport heat from a source to a sink in the absence of a pump, using the forces induced by the thermal expansion of a working fluid to circulate it.

Measurement of the Indoor Air Temperature Distribution using Acoustic Travel-Time Tomography

, 2023
One of the main criteria determining the thermal comfort of occupants is the air temperature. To monitor this parameter, a thermostat is traditionally mounted in the indoor environment for instance in office rooms in the workplaces, or directly on the radiator or in another location in a room.

Numerical Simulation and Analysis of Gas-liquid Coupled Double-acting Thermoacoustic Refrigeration System

Zhileng xuebao, 2021
A novel type of gas–liquid coupled double-acting traveling-wave thermoacoustic refrigeration system is proposed to solve the low efficiency of traditional thermoacoustic refrigeration with a gas resonance tube.

Analytic solutions for the one-dimensional compressible Euler equation with heat conduction closed with different kind of equation of states [PDF]

, 2012
We present analytic self-similar or traveling wave solutions for a one-dimensional coupled system of continuity, compressible Euler and heat conduction equations. Different kind of equation of states are investigated.

A study of Traveling Ionospheric Disturbances and Atmospheric Gravity Waves using EISCAT Svalbard Radar IPY-data [PDF]

Annales Geophysicae, 2011
We present a statistical study of Traveling Ionospheric Disturbances (TIDs) as observed by the EISCAT Svalbard Radar (ESR) during the continuous IPY-run (March 2007–February 2008) with field-aligned measurements.
