DISPLAY
A free turbulent plane jet is formed when fluid emerges steadily
from a wide slot into a reservoir of the same fluid at rest.

Downstream of a 'development length', of about 8 slot widths, the
flow becomes self-similar.

In the self-similar region of the jet, both the velocity and
temperature half-widths vary in proportion to z, and the centre-
line velocity and temperature excess decay as z**(-0.5).

The calculations are started at z = 0, where the velocity is
supposed to have a "top-hat" shape, with a uniform value from
y = 0 to y = half the slot width, and a much smaller value for
larger values of y.

The grid width and forward step are set to increase linearly
with z.

DISPLAY
As for case 150, but with the Prandtl 1-equation model.
