This document presents an overview of incompressible inviscid flow concepts including doublet flow, vortex flow, uniform flow, source and sink flow. Doublet flow occurs when a source and sink of equal strength are located at the same point, causing rotating flow. Vortex flow is rotating flow around an axis. Uniform flow is when velocity and other properties do not change from point to point. A source flow is fluid radiating outward from a point, while a sink flow is inward to a point, with area of flow decreasing closer to the sink. Diagrams illustrate key characteristics of each flow type.

Vortex Flow A vortex is a region in a fluid in which the flow is rotating around an axis line, which may be straight or curved. Uniform flow The flow is defined as uniform flow in the when in the flow field the velocity and other hydrodynamic parameters do no change from point to point at any instant of time. Source and sink A radially symmetrical flow field directed outwards from a common point is called a source flow .As the fluid outward , the area of flow increase. Sink flow is the opposite of source flow. The streamlines are radial, directed inwards to the line source. As we get closer to the sink, area of flow decreases.
