Abstract

The
heated surface jet discharged into a bay which is connected to a larger body of
water through a strait may experience bifurcation in the bay and stratification
in the strait. The combined effects of bifurcation and stratification may lead
to a substantially greater rise in temperature than the rise expected in case
of unrestricted receiving body of water. In this study, the behavior of heated
effluents discharged into bays with a restricted access to a large body of
water is scrutinized experimentally by the help of a scaled physical
model.Dimensional analysis leads to a new dimensionless parameter Ar, area
restriction parameter, on which the difference between the excess temperatures
at the inlet of the strait for restricted and free receiving mediums, Δ(ΔT/ΔT₀) is shown
to be strongly dependent.
