5. Stream Function
Stream functions play a crucial role in the analysis of fluid flow, facilitating the examination of two-dimensional and compressible flows. The chapter emphasizes the mathematical formulation of stream functions, their application in computational fluid dynamics, and the visualization of flow around objects like the F-16 fighter jet. A comprehensive understanding of streamlines and their derived properties aids engineers in solving complex fluid mechanics problems.
