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. The large container has a
separate floor, so that its top part can be filled with
water. 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 contains cut-
outs which allow you to evenly mark the flow with
colour.
