Solar ponds are bodies of water in which heat convection resulting
from the absorption of solar radiation is suppressed by an
artificially established salt concentration gradient.
In this thesis a new method of heat extraction from the pond was
investigated, both theoretically and experimentally. The method
consisted of extracting heat from the whole body of the pond by means
of a helical coil heat exchanger. Because of the existence of a
temperature gradient through the depth, the overall efficiency of
such a solar collector was expected to increase. The developed
theory of this system based on the steady state heat transfer theory
predicts the effect of operating parameters such as insolation, flow
rate and design parameters (such as length of the heat exchanger) on
the pond and outlet fluid temperature and the efficiency. [Continues.]
