Tilavuuslähteet
Tilavuuslähteet, or volume sources, refer to phenomena or objects that emit something, such as heat, light, or particles, from a region of space rather than from a single point or surface. In physics and engineering, this concept is often used to simplify complex emission processes. Instead of calculating the emission from every infinitesimal part of an object, its contribution can be approximated as if it were emanating from a continuous volume.
This simplification is particularly useful in fields like heat transfer and radiative transfer. For instance, when
The concept of tilavuuslähteet contrasts with point sources, line sources, and surface sources, which represent emissions
