能量损失系数 meaning in English
coefficient of energy loss
energy-loss factor
Examples
- During the hydraulic calculation on pipeline network , it is unacceptable to neglect local energy loss or to adopt constant local energy loss coefficients
进行管网水力计算时，忽略结点处的局部能量损失或采用不变的局部能量损失系数均是不合适的。 - The study result also shows that there is significant energy exchange between all the pipe sections connected to the same junction , therefore , those flow phenomenon can not be accurately reflected if neglecting or adopting the constant energy loss coefficients
研究结果还表明，与同一结点相接的各管段间存在显著的能量交换，因此，忽略或采用恒定不变的能量损失系数均不能正确地反映这些水流现象。 - A calculation comparison on the pipeline network system consisting of pipe sections of short length is made herein with three calculation methods respectively , i . e . neglecting the local energy loss at junctions ; adopting constant local energy loss coefficients and the semi - empirical relationships based on experimental data related to the flow conditions , from which the calculated results for the flow rates of the pipe sections are largely deviated
文中分别应用三种计算方法，即忽略结点处局部能量损失、采用恒定不变的结点局部能量损失系数，以及根据试验成果所得的与水流条件有关的半经验公式，针对短管段构成的管网系统进行了计算比较，管段流量的计算结果相差很大。 - From this point of view , a general analytic expression for the coefficient of local energy loss was presented based on the principle of hydrodynamics , together with experiments on particular flow characteristics and energy dissipation mechanism at right - angle junctions , and the expression was validated with the experimental data
为此，根据水动力学基本原理，在分析90汇流口独特水流特性及能量耗散机理的基础上，提出了局部能量损失系数的综合表达式，并应用试验资料对该综合表达式进行了验证。
