streamline

The line traced by a liquid or gas as it moves. Streamlines are most commonly used in describing the flow of a liquid or gas around a solid object.

Note

A “streamlined” design is one in which objects that move through a gas or liquid are shaped to match these lines, and therefore reduce the energy required to produce that motion.
