| Abstract: | As it is difficult to solve the problem of unsteady-state heat transfer in theory,study of flat plate solar collectors in series-connected system with intermittent output is conducted by numerical simulation.Under the unsteady-state heat transfer condition,the impact of the diameter and center distance of solar collectors on the instantaneous collector efficiency and water production rate per square meter are discussed respectively.The results show that flat cartridge collector performed high effeciency.And... |
