Computational Fluid Dynamic Analysis of a Greenhouse for Urban Farming
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 10
Abstract
Greenhouse engineering implementation along with thermodynamic condition maintenance can create a new revolution even in moderate climatic conditions of India, It can produce off seasonal crops and medicinal plants to reach required output healthy living our densely populated country. In this paper, the climate optimization problem in an innovative design made with glass greenhouse is studied with respect to the thermal behavior of geothermal heated greenhouses. The experimental greenhouse and the present report will be a useful tool in choosing the control system for it. The results obtained with the simulation system will also be helpful in convincing many other greenhouse engineers and entrepreneurs of India to successfully maintain thermal conditions of the greenhouse the most economical way to save energy and improve production by constructing properly designed high structures and control systems. The model includes the effects of solar radiation, cooling (with both a soil surface damping system and a heat sink cooling system in use when the outside temperature is high), Ventilation, infiltration, evaporation, and condensation. In this paper the dynamic simulation/ CFD Analysis will be presented, being the model used for modeling the green house. In addition to giving protection from the effects of wind, rain and snow, the temperature inside the greenhouse is increased during the day by solar radiation. As the rate of plam growth is doubled for a 10 K rise in temperature up to a certain limit, higher temperatures are important for the economic production of commercial crops in greenhouses, and some pretentious species require greenhouses to be heated at night as well as during the day. To predict the temperatures which occur naturally in a greenhouse, and the energy needed to achieve a desired temperature, requires an understanding of its thermal behavior.
