Document Summary
Lagrangian: by tracking the motion of individual particles as a function of time. Eulerian: by considering the flow properties in a space. Rather than tracking individually particles, we take a point in space and identify all the properties of that point" We"re gonna be applying the conservation laws to the. We"re tracking how the particles moves through a fluid in a period of time. Lecture notes page 1 g e p g p. It shows you where all the particles that pass through that point travel downstream from that point. If you"re looking at flow along the streamline, the streamline has to be in the same direction of the flow. Because of that, streamlines are the most useful method of visualizing fluid flow because it tells us information about mass, momentum and energy. A steady flow with respect to time causes all three to be the exact same thing.
