This case represents the flow in a circular duct that has an
abrupt enlargement at the inlet.The duct wall is held at a
constant temperature.
Auxiliary relations comprise a turbulence model similar to that
of Prandtl. The length scale distributions are determined as of
the type proposed by Ranchal and Spalding in 1972 ( J. of Waerme-
und Stoff Uebertragung, 5, 1972 )
PLANT is used to introduce the codings for length scale
distributions guided by the formulae provided in Group 9 in the
string marked PRPT01.
