Numerical simulation and experimental validation of solar greenhouse dryer using finite element analysis for different roof shapes

The word greenhouse dryer is used for a building which is highly glazed with thermal conditioning for desired range and it is used for cultivating crops, plants, vegetables, etc. The actual working of a greenhouse is that the short-wave radiations falling on the greenhouse are absorbed by the outer glazing material thereby heating the interior area of greenhouse and providing ambient heat for plants, vegetables growth respectively. The heated space is retained within the enclosure of greenhouse. This phenomenon is called as greenhouse effect. The important role played during the greenhouse effect phenomenon are atmosphere, insulating roofs, walls, etc. The current study focuses on the numerical and experimental validation of Solar Greenhouse which is utilized for drying phenomenon. The numerical simulation is performed using Finite Element Analysis method. The various roof shapes have been incorporated to have emphasis on maximum solar gain to drying phenomenon.
