Convective heat transfer in Thermography or Thermal Imaging

Convective heat transfer is one of the most important modes of heat transfer in engineering, physics and thermal science. It occurs in a moving medium and is most commonly associated with the transfer of heat between a solid surface and a moving fluid such as air, water, or any gas or liquid. In many practical situations, heat does not simply travel through stationary materials but is carried away by fluids that are in motion. This movement of fluids allows heat to be transported more efficiently than by conduction alone. Because of this reason, convective heat transfer plays a vital role in many natural processes as well as industrial applications such as thermal imaging, heat exchangers, cooling systems, weather patterns and many other engineering systems. Convective heat transfer generally occurs when a fluid moves across the surface of a solid body that is either hotter or colder than the fluid. When the solid surface has a higher temperature than the surrounding fluid, heat flows …
