This paper presents the law of maximum rate of energy dissipation as the sec- ond law of continuum dynamics in addition to the classical,conservation laws refered as the first category of laws. Only by the simultaneous application of both laws may a dynamic problem be solved. It is suggested that the law may be extended to the realm of molecular theory. General formulas for the second law of fluid dynamics and appled hydraulics are proposed. It is shown that the corollaries of the law are Castigliano's theorem...

This paper presents the law of maximum rate of energy dissipation as the sec- ond law of continuum dynamics in addition to the classical,conservation laws refered as the first category of laws. Only by the simultaneous application of both laws may a dynamic problem be solved. It is suggested that the law may be extended to the realm of molecular theory. General formulas for the second law of fluid dynamics and appled hydraulics are proposed. It is shown that the corollaries of the law are Castigliano's theorem of least works in mechanics of solids and Belanger-Boss theorem of minimum specific energy in applied hydraulics.

本文对连续介体动力学中现有诸经典守恒定律作为第一类定律以外,提出另一最大能量消散率定律作为第二定律;惟有两类定律同时应用,才能解答一动力学问题。这个新定律也可引伸到分子物理学的范畴。文中建立了流体动力学和应用水力学第二定律的一般方程;并证明了固体力学中卡斯的格里诺最小功学说及应用水力学中培纶格—波丝最小特定能量学说为第二定律的推论。

This paper adopts a double-porosity model and nonlinear two-term law of flow in porous media. For one dimensional flow, the basic equations of two-phase displacement in cavernous-fractured reservoirs are derived, then solved numerically by using the method of characteristic. After comparing it with linear result, essential characters of nonlinear effect and oil displacement by water from naturally cavernous-fractured reservoirs have been revealed and clarified.

The whole paper consists of two parts (Part J and Part I ). In Part J , we shall analyze the relation between the two theories of turbulence involving large Reynolds number, the Markov process theory from the Lagrangian joint of view and Kolmogoroff's theory from the Eulerian point of view. It will be oointed out that the Reynolds number being needed for the Markovian description of turbulence should be as large as that is needed for Kolmogoroff's second hypothesis, that the eddies of the period of order T?(the self-correlation time scale of the random velocity u) and the eddies of the period of order T, (the self-correlation time scale of the random force f) correspond to the energy-con taining eddies and the eddies in the dissipation range respectively, and that , the time interval for the applicability of Richardson's law during two-particle's dispersion, corresponds to the inertial subrange in Kolmogorof f s theory. Thus, these two theories reflect the property of the turbulence involving very large Reynolds number from different aspects.

本文全文分为两部分(Ⅰ和Ⅱ).第Ⅰ部分讨论了关于大雷诺数湍流的两种理论——拉格朗日观点的Markov过程理论与欧拉观点的Kolmogoroff理论之间的联系.指出:对位置和速度的联合过程进行Markov描述所需雷诺数与Kolmogoroff第二相似性假设所需雷诺数同样大;周期与T_u和T_f同阶的旋涡分别对应于Kolmogoroff理论的含能范围与耗损范围;Richarson定律的适用范围T_*≤t≤β~(-1)对应于Kolmogoroff理论的惯性子范围,从而指出,两种理论从不同侧面反映了大雷诺数湍流的流场结构.在本文第Ⅱ部分,我们将利用第Ⅰ部分中阐述的物理想法以适当方式建立两种理论之间的某种定量的联系.从而由拉格朗日观点的弥散运动的结果得出欧拉观点的结构函数、关联函数和能谱函数.所得结果不但适用于惯性子范围,而且适用于尺度更大(或波数更小)的全部范围.熟知的Kolmogoroff“2/3定律”和“(-5)/3定律”为本结果在惯性子范国的渐近解.因而本结果是Kolmogoroff“2/3定律”和“(-5)/3定律” 的推广.
