Thermal performance of natural convection solar air collector with conical surface geometry for vertical application (original) (raw)
In this study, a new absorber plate was designed and manufactured to improve the thermal efficiency of the solar air collector (SAC). Thermal performance of solar air collector with conical absorber plate (Conic type) of has been experimentally investigated and the collector with flat absorber plate (Flat type) is used for comparison. The average thermal efficiencies obtained are 35.8% and 44.7% for both Flat type and Conic type respectively for natural convection conditions. According to the data obtained in the experiment, a model of artificial neural network (ANN) of the collector is created considering three inputs and one output data. By training an ANN with a part of the experimental results, the output parameter is estimated corresponding to different inputs data. In conclusion, the heater thermal performance is significantly improved by conical obstacles on the absorber plate and the ANN model can easily be implemented to predict the thermal efficiency of the solar air collectors.
