ABSTRACT
This paper presents laboratory results and a formulation for predicting the
length of arrested salt wedges formed in horizontal circular outfall pipes.
The
formulation is based on a combination of the energy and the momentum
equations.
A new expression for the friction factor which takes into account
the effect of the two-layer stratification is suggested.
Two circular outfall
pipes having internal diameters of 5 and 13.
75cm were used to conduct the
tests and a wide range of various combinations of experimental parameters
(saltwater density 1.
01 to 1.
032g/cnf and densimetnc Froude number 0.
42 to
0.
92) were used.
Measurements of the length of the arrested salt wedge and
velocity distributions (for the pipe with diameter = 13.
75c...
