Flat Plate Solar Water Heaters are extensively used all over the world to utilize the natural source of solar energy from sun. In order to utilize the solar energy during off sunshine hours it is inevitable to store and retain solar thermal energy as long as possible. For effective gain and retention of solar thermal energy a fins are provided. Depth of fins immersed in water, V-grooved and dimpled absorber surface in a solar thermal collector are important geometric parameters that influence the maximum temperature rise during peak solar irradiation and hence the losses. CFD studies show an improved heat transfer with increase in depth of fin. Source

Flat Plate Solar Water Heaters are widely used all over the world to utilize solar energy available abundantly in nature. To utilize solar energy during off sunshine hours, it becomes necessary to store the solar thermal energy and retain it as long as possible. Depth of water in a solar thermal collector is an important geometric parameter that influences Heat retention. A mathematical modelling of transient heat transfer was done for different water depths and validated with experimental studies to optimize the depth of water from maximum temperature and maximum heat retention view point. © February 2015 IJENS.
