The characteristics of mean velocity profiles, velocity fluctuations and interfacial fluctuations in two-layered flows have been investigated using two components of velocity and interfacial displacements measured simultaneously. Experimental results are expressed consistently in non-dimensional forms composed of the interfacial physical quantities. Interfacial fluctuations consist of long periods (L. P. wave) and short periods (S. P. wave), and induce a pair of vortical flows of the cat's eye pattern corresponding to the L. P. and S. P. waves.
