THERMAL BEHAVIOR OF ALARGE SALINITY-GRADIENT SOLAR POND IN THE CITY OF MASHHAD
Abstract–By applying a model of finite differences, the thermal behavior of a large solar pond in the
city of Mashhad in the north east of Iran, is studied in this paper. The 32-year data of sunny hours to
day-length ...
On the performance of a salt gradient solar pond
Abstract
The performance of a laboratory-scale salt-gradient solar pond is described in this paper. Di erent
methods of saline injection to the bottom layer and corresponding temperature and concentration
استخر خورشیدی با گرادیان شوری
در این استخرها انرژی خورشیدی در یک مخزن آبی روباز محتوی آب شور لایه بندی شده جذب و ذخیره میشود.
اولین مطالعات در زمینه استخرهای خورشیدی به سال1958 در اسرائیل آغاز شدو تا سال 1967 ادامه یافت (Tabor, 1981, p.182) ...
Heat extraction from a salinity-gradient solar pond using in pond heat exchanger
Thermal energy extraction from a small salinity-gradient solar pond is studied in this article. The small pond has an area of 4.0 m2 and
a depth of 1.1 m. Fresh water circulates through an internal heat exchanger, ...
Thermal behavior of a small salinity-gradient solar pond with wall shading effect
Abstract
The thermal behavior of a small-scale salinity-gradient solar pond has been studied in this paper. The model of heat
conduction equation for the non-convective zone has been solved numerically with ...
کاربرد روش چند شبکه ای برای حل دستگاه معادلات خطی در تحلیل هیدرولیکی شبکه لولهها
الگوریتم های گرادیان از معروف ترین روش های تحلیل شبکه لوله ها به شمار میروند. حل دستگاه معادله خطی، بیشترین هزینه محاسباتی را در روش های گرادیان داراست بخصوص برای شبکه های بسیار بزرگ که بیش از هزاران متغیر داشته باشند. ...
Hydraulic Analysis of Water Distribution Network Using Shuffled Complex Evolution
Hydraulic analysis of water distribution networks is an important problem in civil engineering. A widely used approach in steadystate analysis of water distribution networks is the global gradient algorithm (GGA). However, ...
Particle Swarm Optimization for Hydraulic Analysis of Water Distribution Systems
Abstract: The analysis of flow in water-distribution networks with several pumps by the Content Model may be turned into a non-convex optimization uncertain problem with multiple solutions. Newton-based methods such as GGA ...
TOWARDS THE DESIGN OF LOW MAINTENANCE SALINITY GRADIENTSOLAR PONDS
Abstract—Applications of simple methods to reduce the maintenance of a small solar pond are discussed in
this paper. It was found that floating rings along with continuous surface flushing could effectively control ...
