CFD and Steady State Thermal Analysis of Solar Water Heater

             Difficulty in collecting conventional energy sources as well as their economic benefits including saving of time, money, fertilizer of higher nutrient value, availability of waste easy and comfortable cooking, health benefits including the reduction diseases and environmental benefits such as saving of forest, clear surrounding were the main motivational factors for this research. However, climate temperatures in areas are too low to enable enough biogas production in small unheated digesters to meet the energy requirements of the institute, so the objectives of were to overcome the problem of energy by solar assisted with the hot water storage tank. In this research mathematical modeling of the solar water heater was designed and the analysis of heat transfer coefficient (losses) through the flat plate collector was done.

           Solar energy is becoming an alternative for the limited fossil fuel resources. One of the simplest and most direct applications of this energy is the conversion of solar radiation into heat, which can be used in space or water heating systems. A commonly used solar collector is the flat-plate. This flat plate collector absorbs the incoming solar radiation, converts it to heat at the absorber plate, and transfers this heat to a fluid flowing through the collector. The fluid is usually air or water. The warmed fluid carries the heat directly to the hot water or space conditioning equipment. This paper presents a precise and detailed analysis of a solar flat plate collector.
