Rational design of non-convective zone of salt gradient solar pond considering turbidity and biological growth in water.

Abstract

The optimum size of non-convective zone of a Salt Gradient Solar Pond is determined from the heat balance considerations of the storage zone. The equation governing heat flow in storage zone are simplified considering a linear heat flow through the storage zone to the upper convective zone.The radiation absorption in pond liqui d is estimated c onsideri ng the effect of various Environ mental parameters in pon d like turbidity and biological growth in it. This has made the analysis more confirming to the real work situation for a pond. The ambient parameter like temperature and radiation are accounted to vary hourly. One significant observation is that the influence of turbidity on pond’s performance is so drastic that at turbidity value higher than 0.8\NTU, the optimum Non-Convective Zone (NCZ) size is not obtained analytically.
