An Experimental Investigation of the Effect of Finite Amplitude Internal Waves at the Interface Between Two Miscible Fluids on the Density Profile.

摘要

Shear stresses in the interfacial layer created by finite amplitude internal waves can create unstable conditions and thus the formation of high frequency internal waves. These high frequency waves can enhance the diffusion of salt into the upper layer and affect the mass density profile. The effect of these waves on the density profile is experimentally investigated in this thesis. Finite amplitude internal waves were generated for long periods of time and density profiles measured periodically. The experiments were performed in an internal wave facility which is eighty feet long, four feet high and two feet wide. The internal waves were generated by a hydraulically driven horizontal diaphragm located at the interface and at one end of the tank. (Author)
