The cross-flow wind turbine is because suited for using the areas where the wind direction changes frequently because it's structure is independent of the wind direction. In order to improve it's performance, it is indispensable to analyze the air flow from the entrance to the exit of the wind turbine. However, in most casses only the outside of the wind turbine has been analyzed in the past research. In this research, the experiment were conducted for the purpose of visualization of the flow inside the wind turbine.The experiments were conducted at tip speed ratios of 0.2, 0.4, and 0.6, and the difference between the visualization results. Results show that the size of the vortex, which abstracted the internal flow of the wind turbine, was the smallest at a tip speed ratio of 0.4, where the maximum efficiency of 0.1 was attained.
