Streamlines

Definition

Streamlines are visual representations of the flow of a fluid, depicting the trajectories that fluid elements follow. In the context of molecular properties, streamlines can help illustrate how molecules move through space or how they interact with forces, providing insights into dynamic processes like diffusion and chemical reactions.
