Abstract
Experiments and numerical calculations were carried out on the dynamic behavior of the solitary wave of a flowing liquid. Data on the wave propagation velocity, the wave profile, and the liquid velocity profile were presented. Results of the numerical calculations agreed with the experimental results in respect of the above-mentioned qualities which characterize the solitary wave. Thus, the applicability of this numerical calculation method was verified. Based on the experimental results and the numerical calculations, simple correlation equations, which express the relationships between the solitary waves of the stationary liquid and of the stratified liquid flow were deduced. The applicability of Benjamin's theory on the solitary wave of a flowing liquid was also verified.
