Momentum transport and torque scaling in Taylor-Couette flow from an analogy with turbulent convection
Convection and heat transfer Taylor-Couette flow
2011/8/31
We generalize an analogy between rotating and strati ed shear ows. This analogy is summarized in Table 1. We use this analogy in the unstable case (centrifugally unstable ow v.s. convection)to compute...

A theoretical study on the psyche of a captain operating in confined sea is made from the view point of thermodynamic analogy. A relationship which corresponds to the PVT system in thermodynamics is f...
大连理工大学工业装备结构分析国家重点实验室研究成果：结构力学与最优控制之间的模拟理论 Analogy between Structural Mechanics and Optimal Control
大连理工大学工业装备结构分析国家重点实验室研究成果 结构力学 最优控制 模拟理论
2008/3/9
基于结构力学与最优控制的模拟理论，提出了基于2N类算法的精细积分法，并给出求解状态反馈
控制问题及 滤波问题中黎卡提微分方程的精细积分方法。现已证明 状态反馈控制及 滤波中的最优参数对应于结构力学中结构振动的基本固有频率，从而可用扩展的Wittrick-Williams算法结合Riccati方程的精细积分算法计算这一最优参数。以此为基础，进一步将算法用于求解更为一般的

Understanding Air-Core Photonic-Bandgap Fibers:Analogy to Conventional Fibers
Air-core photonic-bandgap fi bers conventional solid-core fi ber LP modes numerical aperture PBF
2015/8/11
It is shown from basic principles that the core modes of an air-core photonic-bandgap fiber (PBF) exhibit similar qualitative and quantitative behavior as the linearly polarized (LP)modes of an ...
The analogy method for the description of external characteristic of inner combustion engines
external characteristic of inner combustion engine vehicle dynamics torque function load coefficient analogy method summarized characteristic
2010/11/2
The original data for the evaluation of vehicle motion dynamics is external characteristic of its engine, which consists of three parameters: torque, power and specific fuel consumption. It is very im...
