本文研究了弯曲管内振荡流体的非线性流动效应。对管道横截面内的二次稳定速度场进行了详细的研究。我们的实验结果与Lyne（1970）的理论（他的理论中对雷诺数Rs [Lt] 1有效的部分）和Zalosh & Nelson（1973）的理论进行了比较。在这些比较的基础上，我们得出结论，这些理论在实际中适用于比正式预期的更高的雷诺数。
This paper deals with nonlinear streaming effects in an oscillating fluid in a curved pipe. The secondary steady velocity field in the cross-sectional plane of the pipe is studied in detail. Our experimental results are compared with the theory of Lyne (1970; that part of his theory which is valid for Reynolds numbers Rs [Lt ] 1) and the theory of Zalosh & Nelson (1973). On the basis of these comparisons we conclude that the theories are in practice valid for higher Reynolds numbers Rs than was formally expected.
