The term that describes a heat transfer method involving the movement of fluids is convection. This process occurs when warmer, less dense fluid rises while cooler, denser fluid sinks, creating a circulation pattern. This movement of fluid facilitates the transfer of heat energy from one area to another.

In practical applications, such as in sewage treatment, convection plays a significant role in processes like aeration and mixing, helping to evenly distribute temperature and nutrients throughout a fluid medium. This is particularly important for maintaining optimal conditions for microbial growth and treatment efficiency in sewage systems.

Convection is distinct from conduction, which is the transfer of heat through direct contact between materials, and radiation, which involves the transfer of heat through electromagnetic waves, requiring no medium. Capacitance, on the other hand, relates to the ability of a system to store electrical charge and is not related to heat transfer methods.
