Doublet Flow
The doublet occurs when a source and a
sink of the same strength are collocated
the same location, say at the origin.
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.
