再论普朗特混合长度理论

Further discussion on the theory of Prandtl's mixing length

从世俗的现象比喻论、混合长度递增论和混合长度分区论,说明普朗特混合长度理论违背了流体力学的连续介质定义,违反了流体力学的相似法原理,用其一系列的理论和公式证明普朗特混合长度理论是一个错误的理论。

From the common customs discussion of phenomenal analogy,constant increasing theory and subregion theory of mixing length,it is illustrated that the definition of continuum medium in fluid mechanics has been disobeyed and the principle of similarity method in fluid mechanics has been violated by Prandtl＇ s mixing length theory.It is demonstrated that the Prandtl ＇ s mixing length theory is a wrong theory by analyzing a series of his theory and formulas.
