Mechanisms of Heat Transfer II01:20

Mechanisms of Heat Transfer II

3.2K
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...

There are three methods by which heat transfer can take place: conduction, convection, and radiation. Each method has unique and interesting characteristics, but all three have two things in common: they transfer heat solely because of a temperature difference; and the greater the temperature difference, the faster the heat transfer.
In order to solve a problem related to heat transfer, first of all, the situation needs to be examined to determine the type of heat transfer involved. This could...

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.

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.

Area of Science:

  • Optics and Photonics
  • Materials Science
  • Thermal Imaging

Background:

  • Infrared cameras cannot image through hot windows due to intense thermal emission.
  • High temperatures obscure objects behind windows, limiting thermal imaging applications.

Purpose of the Study:

  • To enable infrared imaging through hot windows.
  • To overcome the challenge of thermal emission blinding cameras.

Main Methods:

  • Coating a hot window with an asymmetrically emitting infrared metasurface.
  • Engineering the metasurface's imaginary index of refraction.
  • Utilizing nanoscale resonators for controlled absorption losses.

Main Results:

  • The metasurface-coated window suppresses thermal emission towards the camera.
  • The window remains sufficiently transparent for thermal imaging.
  • Achieved double the thermal imaging contrast compared to a control window at 873 K.

Conclusions:

  • Metasurface coatings offer a viable solution for thermal imaging through hot windows.
  • Engineered optical properties can overcome limitations of thermal emission.
  • This technology enhances the capabilities of infrared imaging systems.
