What is the process of conduction in fire dynamics?

Conduction is a fundamental mode of heat transfer that occurs when thermal energy is transmitted through a solid material without any movement of the material itself. In this process, heat moves from the hotter part of the solid to a cooler part due to the vibration and interaction of particles within the medium. The energy is transferred through collisions between atoms and molecules.

In the context of fire dynamics, understanding conduction is critical, as it can influence how heat spreads through materials during a fire. For example, in a burning building, the heat from flames can conduct through walls, floors, and structural elements, impacting the integrity of these components and potentially leading to structural failure.

While heat transfer can occur through gas movement, such as convection, and through electromagnetic waves, such as radiation, these mechanisms are distinct from conduction. In conduction, the emphasis is on the transfer of heat through a solid. Therefore, recognizing conduction as the transfer of heat through a solid medium is crucial for grasping the principles of heat transfer in various fire-related contexts.
