Seasonal temperature variation of solar pond under Mediterranean condition

ABSTRACT
In this paper, thermal performance of solar pond for different condition was numerically investigated by using Discrete Ordinates Method to facilitate a greater understanding of the effects of relative various condition on thermal performance improvement of solar pond. For this, a 3D prototypes of solar ponds with square cross sections were simulated for the oversoil and subsoil, insulated and uninsulated, open on and off conditions. The direction of sunlight (zenith angle and the solar elevation) was automatically computed from the latitude, longitude, time zone, date, and time. The estimated solar position is accurate for a date between year 2000 and 2199, due to an approximation used in the Julian Day calendar calculation. Seasonal temperature variation of solar pond was calculated for the full period of one year starting from March and calculated data were compared with experiment to validate simulation accuracy of heat transfer model. Result indicates that temperatures in the summer time were calculated at around 55 °C, while temperatures in the winter were in the range of 20 to 30 °C and temperature changes between 30°C and 40°C in spring and autumn.
