摘要

本文提出了一种计算等截面渠道水力学阻力的新方法。该方法是基于得到的紊流平均能量耗散率的估计。论文的第一部分是对该方法的理论论证。第二部分是用上述方法计算各种渠道的水力阻力，并与已知结果进行比较。该方法仅基于沟道的几何信息，能够以足够高的精度计算各种沟道的水力阻力。

Determination of hydraulic resistance of channels using spectral geometry methods

In this paper, we propose a new method for calculation of hydraulic resistance of channels with constant cross-section. The method is based on the obtained estimates for the average energy dissipation rate in a turbulent flow. The first part of the paper is devoted to theoretical justification of the method. The second part is devoted to calculation of hydraulic resistance of various channels using the above-mentioned method and comparison of these values with the known results. The proposed method allows for calculation of hydraulic resistance of various channels with sufficiently high accuracy and is based only on the information about the channel geometry.
