1. Description
The laminar flow apparatus can be used to demon-
strate and examine the laminar flow in water.
It enables experiments which focus on the following
subjects:
Development of flow in water
Streamline curve of a linear laminar water flow
Streamline curve around objects with various
shapes
Streamline curve around a wing of an aero-
plane with different angles of attack
Streamline curve at a narrow point
The laminar flow apparatus consists of two cuboid
acrylic glass containers mounted one inside the
other. The large container has a separate floor, so
that its top part can be filled with water. This top
part also contains a few layers of fleece, which par-
tially bind the water. It is therefore possible to
transport the equipment without spilling water out
of the container. The bottom container collects the
overflowing water. The water flows along rectangular
sheets of velour paper, whose top ends point into
the large container. The velour paper sheets have
cut-outs, which allow you to generate various flow
curves. A mask is put onto the velour paper. It con-
tains cut-outs which allow you to evenly mark the
flow with colour.
