you in the model Experiment profiles of laminar flow will be demonstrated In this apparatus used to produce streamlines 2 containers
holding water and Inc respectively all drains through 2 sets of holes which are displaced relative to each other at ch
and
to as the
fluids flow through the narrow gap between 2 glass plates streamlines of formed this flow cold he'll shoal flow after its inventor is a model for the flow of an ideal frictionless fluid the so called potential flow but
here the he'll full flow is
constrained by a constriction
you you
OK In the constriction the
streamlines become narrower which means that the fluid must speed up
now around disk is inserted between
the glass plates
you
to give the patent and more symmetrical appearance of
course without changing the flow in any way the disk is moved slightly to 1
side now 1 of the streamlines hits
the disc in the center you it
divides and then merges again below the desk here a plate is inserted
initially parallel to the streamlines and what
but
now at an angle do
finally at 90 degrees if you
you note that in the steady state this profile is completely symmetrical above and below the plate as is to be expected for a frictionless potential flow you you you the
you now the potential flow around an F for all will be modeled using the
usual flow
yeah we
In the following several different angles will be tried the use of the of
this is close to the angle at which the wing of an airplane moves through the air of yeah
of we
yeah

Abstract The goal is the demonstration of two-dimensional streamline patterns as they occur when non-viscous fluids flow around obstacles. The patterns shown are models, since they have been produced in a viscous fluid under conditions of laminar flow.
