Abstract

The main
cause of heated water discharges is the use of seawater as a coolant by power
plants and industrial manufacturers. Uncontrolled discharges into the ambient
sea water having excess heat, have a negative effect on the ecosystems. In this
study, the near field dilution of heated sea water discharges is modeled and
the behaviors of pollutant clouds are analyzed using CORMIX (CORMIX2). The
effects of different parameters such as total effluent discharge, diffuser
length, port details, current on the near field dilution of heated discharges
are investigated with different scenarios by numerical models CORMIX2, which is
the submodule of CORMIX for submerged multiport diffusers. In spite of a
hypothetical study, a real coastal region was selected to obtain and discuss
realistic conditions. Since Tekirdağ coasts are surrounded by industrial
manufacturers and also agricultural areas, they are under pressure of the
coastal pollution. Therefore Tekirdağ coastal region is selected and CORMIX2 is
applied to determine the effects of discharge parameters on near field
dilution.
