Streamlines And Potential Lines — Lesson 1

This lesson covers the concept of flow through porous media, focusing on the application of continuity in fluid mechanics to understand and visualize the flow in a porous medium. The lesson introduces the concepts of streamlines and stream tubes, which are commonly used in petroleum engineering and oil and gas reservoir simulation. It also explains the use of stream function and potential function to represent the flow. The lesson further discusses the concept of complex potential, which combines the potential function and stream function, and its application in understanding the resultant velocity and direction of flow when multiple elemental flows are present.
