摘 要: 引入最大信息熵原理对明渠均匀流中的污染带问题进行研究,给出了在恒定点源和横向均匀线源情况下稳态污染带浓度场和带长的解析解.传统的不受岸壁干扰时的浓度场公式是本文公式的特殊情形. The principle of maximum communication entropy is employed to study the transverse spreading of the plume in uniform open channel flow in this paper.The analytical solutions of concentration distribution and the formulas for complete mixing distance of steady point source and transverse steady uniform line source have been derived theoretically.The traditional analytical solution of concentration distribution for steady point source with no sidcwall effect is a special case of these solutions.
