Internal wave wake characteristics of submerged vehicle in a stratified ocean are research hotspot at home and abroad. Horizontal Digital schlieren measurement system was constructed to measure the wave height field in pycnocline. Measured wave height and angle were used to verify the reliability of the numerical simulation, and the conclusion of regularity was obtained. With the increase of the velocity, the angles of the internal wave wake were decreased. The maximum wave heights were increased and then decreased with the increased the velocity, and the maximum wave height presents a maximum value when the Fri = 1 in all experimental states.

摘要

Internal wave wake characteristics of submerged vehicle in a stratified ocean are research hotspot at home and abroad. Horizontal Digital schlieren measurement system was constructed to measure the wave height field in pycnocline. Measured wave height and angle were used to verify the reliability of the numerical simulation, and the conclusion of regularity was obtained. With the increase of the velocity, the angles of the internal wave wake were decreased. The maximum wave heights were increased and then decreased with the increased the velocity, and the maximum wave height presents a maximum value when the Fri = 1 in all experimental states.
