In this study, the problem of brine discharge into sea is studied numerically. A 3D model
for the heat and brine dispersion in the vicinity of discharge and intake ports is developed
using Fluent package. The flow is taken turbulent and the fluid properties are considered
variable with salinity and temperature. The results are expressed in terms of streamlines,
isotherms, and salinity contours as well as velocity, temperature, and salinity profiles. These
results give the excess temperature and salinity relative to the nominal values of the free

This theoretical study shows the technical feasibility of self-powered geothermal desalination of groundwater sources at <100 °C. A general method and framework are developed and then applied to specific case studies. First, the analysis considers an ideal limit to performance based on exergy analysis using generalised idealised assumptions.
