摘要：In order to visualize a turbulent concentration field by numerical simulation or laboratory experiment, the spatial resolution smaller than the smallest length scales of concentration field (the Batchelor scale) is required. The Bathelor scale is much smaller in a liquid flow with a high Schmidt number than the smallest velocity scale (the Kolmogorov scale). It is, therefore, very difficult to visualize the concentration field in liquid flows by the conventional methods. In this manuscript, direct numerical simulation and planar laser-induced fluorescence measurement technique in a laboratory experiment in order to visualize the liquid turbulent flows is explained with examples based on my research.
