摘要：

Different designs of solar air heaters with variable width of the flow channels are investigated. Four possible geometries for the flow passage are considered with the aim to improve the efficienc of the system by maintaining a constant temperature of the absorber plate. Efficiencies and plate temperatures are calculated for various designs, among them the most efficient is the one with decreasing duct width. © 1990.
