What does heat transfer describe?

Heat transfer describes the movement of energy from a warmer object to a cooler object. This fundamental principle is central to understanding thermal dynamics and how heat interacts with various materials. In the context of drying applications, recognizing that heat energy naturally moves from areas of higher temperature to those of lower temperature is crucial for effectively managing drying processes.

When a warmer object, such as a heated air mass or wet material, comes into contact with a cooler surface, heat will always flow towards the cooler surface until an equilibrium is reached. This movement of energy is vital in drying situations, as it can expedite evaporation and moisture removal, making heat transfer a key concept in applied structural drying.
