Langmuir circulations are secondary circulations in the surface layer of lakes and oceans, whose axes are parallel to the wind direction. The wave and current interaction theory called CLII theory is well known as the formation mechanism of Langmuir circulations. However, it has not been verified completely yet. In this study, flow visualizations adding the surfactant to the working fluid and numerical simulations using a rigid-surface model were conducted in order to verify the idea that Langmuir circulations are formed without surface waves. Experimental results suggested the formation of these circulations in the case where surface waves were almost suppressed. Numerical results reproduced the experimental results and showed the formation of them without surface waves and sidewalls.
