Item Metadata only Experimental and simulation studies on a single pass, double duct solar air-heater.(Elsevier, 2003-01-01) Forson, Francis Kofi; Nazha, Marouan A. A.; Rajakaruna, HobinaA mathematical model of a single pass, double duct solar air heater (SPDDSAH) is described. The model provides a design tool capable of predicting: incident solar radiation, heat transfer coefficients, mean air flow rates, mean air temperature and relative humidity at the exit. Results from the simulation are presented and compared with experimental ones obtained on a full scale air heater and a small scale laboratory one. Reasonable agreement between the predicted and measured values is demonstrated. Predicted results from a parametric study are also presented. It is shown that significant improvement in the SPDDSAH performance can be obtained with an appropriate choice of the collector parameters and the top to bottom channel depth ratio of the two ducts. The air mass flow rate is shown to be the dominant factor in determining the overall efficiency of the heater.Item Open Access Modelling and experimental investigation of a mixed-mode natural convection solar crop dryer (MNCSD).(De Montfort University, 1999) Forson, Francis KofiItem Metadata only Modelling and experimental studies on a mixed-mode natural convection solar crop dryer.(Elsevier, 2007-03-01) Forson, Francis Kofi; Nazha, Marouan A.
