Segment V6.3: Half-Body

(Related to Textbook Section 6.6.1 - Source In a Uniform Stream -- Half-Body)

Basic velocity potentials and stream functions can be combined to describe potential flow around various body shapes. The combination of a uniform flow and a source can be used to describe the flow around a streamlined body placed in a uniform stream. Streamlines created by injecting dye in steadily flowing water show a uniform flow. Source flow is created by injecting water through a small hole. It is observed that for this combination the streamline passing through the stagnation point could be replaced by a solid boundary which resembles a streamlined body in a uniform flow. The body is open at the downstream end and is thus called a halfbody.
