For precise control of flow, it is necessary to predict the phenomena of non-Newtonian fluid, and understanding of flow phenomena from both experiment and theory is required. However, the time scale in experiments are much slower than calculations by molecular dynamics. To overcome this gap, a high-speed measurement technique with higher time resolution is required. In this study, the time change of the internal structure of the solution was examined using the continuous small angle X-ray scattering spectrum, which obtained by irradiating high-intense X-ray for short time.
