Absorption of Radiation

Absorption of Radiation

The rate of heat transfer by emitted radiation is described by the Stefan-Boltzmann law of radiation:

Radiation: Applications

Radiation: Applications

The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Mechanisms of Heat Transfer II

In convection, thermal energy is carried by the large-scale flow of matter. Ocean currents and large-scale atmospheric circulation, which result from the buoyancy of warm air and water, transfer hot air from the tropics toward the poles and cold air from the poles toward the tropics. The Earth’s rotation interacts with those flows, causing the observed eastward flow of air in the temperate zones. Convection dominates heat transfer by air, and the amount of available space for the airflow...

Mechanism of heat transfer

Understanding heat transfer mechanisms is essential for understanding how our bodies maintain balance in different environmental conditions. When the environment is thermoneutral, the body is in a state of balance, neither using nor releasing energy to maintain its core temperature. However, when the environment is not thermoneutral, the body employs four heat transfer mechanisms to maintain homeostasis: conduction, convection, evaporation, and radiation. These mechanisms facilitate heat...

Mechanisms of Heat Transfer I

Just as interesting as the effects of heat transfer on a system are the methods by which the heat transfer occur. Whenever there is a temperature difference, heat transfer occurs. It may occur rapidly, such as through a cooking pan, or slowly, such as through the walls of a picnic ice box. So many processes involve heat transfer that it is hard to imagine a situation where no heat transfer occurs. Yet, every heat transfer takes place by only three methods: conduction, convection, and radiation.

Mechanisms of Heat Transfer

Mechanisms of Heat Transfer

Heat transfer between the human body and its environment occurs through four main mechanisms: conduction, convection, radiation, and evaporation.
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant...

Summary

This summary is machine-generated.

We calculated heat transfer between 2D Dirac materials like graphene. Near-field heat transfer scales inversely with distance between sheets, but spatial dispersion can limit this law.

Nanoscale heat transfer

Background:

Radiative heat transfer is crucial for nanoscale devices.
2D Dirac materials, such as graphene and topological Chern insulators, exhibit unique electronic properties.
Understanding near-field heat transfer in these materials is key for thermal management in quantum technologies.

Purpose of the Study:

To compute radiative heat transfer between two sheets of 2D Dirac materials.
To derive the short-distance asymptotic behavior of near-field heat transfer.
To investigate the impact of spatial dispersion on heat transfer scaling laws.

Main Methods:

Utilized the local approximation for optical response, neglecting spatial dispersion.
Employed both numerical and analytical methods to derive heat transfer asymptotics.
Focused on 2D Dirac materials including topological Chern insulators and graphene.

Main Results:

Derived the short-distance asymptotic behavior of near-field heat transfer.
Demonstrated that heat transfer scales inversely with the distance between the sheets.
Identified limitations to this scaling law due to spatial dispersion.

Conclusions:

The near-field heat transfer between 2D Dirac materials exhibits an inverse distance scaling at short distances under the local approximation.
Spatial dispersion effects in 2D Dirac materials can invalidate this simple scaling law.
This study provides insights into thermal transport in quantum materials, relevant for nanoscale thermal management.
