英文摘要	The heat transfer process of a solar flat plate collector is analyzed under nonuniform fluid flow distribution, and the corresponding mathematical model is developed. The outlet temperature of every tube of the solar flat plate collector obtained by this model are in agreement with the experimental results, so the accuracy of this model is verified. Using this model, the thermal performances of the solar flat plate collector are analyzed under four kinds of flow distributions, respectively. The calculated results show that the collector heat removal factor and the instantaneous collector efficiency in nonuniform fluid flow distribution are lower than those in uniform distribution, and they are decreased at most by 12.6% and 10.5%, respectively. When the fluid flow distribution is nonuniform, the width of tube fin, the fin efficiency, the efficiency factor, the heat removal factor and outlet temperature of every tube in the solar collector are not equal to each other, and the instantaneous collector efficiency is linear with the normalized temperature difference in the steady state. ©, 2015, Southeast University.
