| Limited sources and rising cost of fossil fuels has instigated researchers to look towards renewable energy resources. Among renewable energy resources, solar energy is required to become indispensable in the future, as it is inexpensive, abundant, inexhaustible, environmental friendly and non-pollutant. Most of the people living in developing countries are dependent on agriculture. Agricultural products are dried to increase the storage life, minimize the packaging requirement and reduce the transportation weight. Solar drying for drying agricultural products is being practiced since long back throughout the world. Because of its drawbacks, advance technique, i.e. greenhouse drying, is being adopted for drying crops to reduce the drying time and... |

| The groundnuts were dried inside an even span roof type free convection greenhouse dryer with a useful floor area of 1.2×0.8 m2 in the environmental conditions of Rohtak, India (28o54’ N 76o34’E). Wire mesh sieves of sizes 0.15×0.25 m2, 0.25×0.4 m2,and 0.35×0.6 m2 were used to accommodate thin layer samples of groundnuts. The groundnuts were dried till the optimum safe moisture storage level (8–10%) was attained. Based on experimental (hourly) observations the values of constants (C and n) in the equation of Nusselt number were evaluated. The values of convective and evaporative heat transfer coefficients were calculated which were observed to decrease with the increase in the sieve size. The overall average greenhouse thermal, energy, and exergy... |
