We now look at
the maths involved in describing axisymmetric flow for an
incompressible, irrotational (inviscid) fluid. Such a fluid is
like water, in which case the topic is called Hydrodynamics. But
we will pretend that air also is incompressible, in which case
the topic is called Aerodynamics. The intention is to provide
the equations used for the previous article,
Part 5, which describe the
flow of air around the nose of an axisymmetric airplane.
The type of maths concerned is called calculus, a subject which
is understood by about .0001% of the Worlds population. I will
make no effort to explain the calculus, unless I have a
neurological fit and realise that I might understand some of it
myself!
The rest of this article is available
in this Acrobat PDF file, as the web-mistress can be bothered
converting all the maths characters to images! My father is so
demanding.
