Abstract

Using fossil fuels causes environmental problems such as greenhouse emissions and air pollution. In this study, the use of solar dryers greatly reduced fossil fuel consumption in Yazd area and reduced environmental pollution in addition to increasing the quality of dried products. This dryer operates by passing natural convection or forced convection between the products and directly depends on the solar radiation received by the collector. To simulate the performance of the dryer, its 2D dimensions were modeling in Gambit software. Using Ansys Fluent software, by applying the amount of heat flux created at different hours in July 2020 for the geographical conditions of Yazd city on the collector, air flow and outlet temperature was reported. Based on the contours and diagrams, it was concluded that with a mass flow rate of 0.16 kg / s and a temperature of approximately 35C°, the drying conditions of grains and vegetables can be provided in the sunny conditions of Yazd.
