查询词典 flow resistance

Based on the compressibility, viscosity resistance and the working house system's deformation etc, flow equations of distribution spool, hydraulic tube and fluid cylinder for 300 MN die forging hydraulic press were established, and dynamics equations of moving beam and upper beam were established based on analysis. The dynamics mechanical-hydraulic coupling model of driving system was established.

By using the said model, the mass flow of flue gas and steam can be calculated on the basis of temperature and pressure concerning the working medium at inlet and outlet of the boiler's heating surface, and the variated amount of the heating surface's thermal resistance can be calculated without using structural parameters of the heating surface.

由于简单换热器模型能够根据锅炉受热面进、出口处工质的温度和压力，计算烟气和汽的质量流量；可以不使用受热面的结构参数，计算受热面导热热阻的变化量。所以，采用该模型开发电站锅炉吹灰优化控制系统，能够解决传统方式存在的流量计算精度低、污垢热阻计算不准确等问题。

In the paper, the steady flow is also included to check the effect on the nonlinear forces with the different wave headings and different side-hull arrangements. From the comparisons of the theory and experiment, we find that the present technique can well predict the added resistance and lateral drifting force for the trimaran ship advancing in waves.

本论文将数值分析之结果与实验值做比较，来验证数值方法分析之正确性，并将稳态项、不同入射波波向以及不同副船体配置的影响加入考虑，来预估三体船在波浪中航行时的附加阻力和横向漂流力，从比较结果可看出本方法预估附加阻力及横向漂流力已有相当不错的结论。
