【Abstract】 A summary on the theoretical, numerical and experimental background materials of internal waves generated by the moving body in stratified ocean is made in present paper. The Green function method, Normal mode decomposition and pole avoidance in the theoretical study is given in this paper. The solution of Wronskian determinant, the solution method of source in the numerical calculation are summarized, and the direct difference computation of internal wave equation with the source and the integral equation method are also introduced. In the experimental studies of internal waves generated by submerged source, two typical experiments in tanks of the stratified flow and some significant experimental results are reviewed. Finally, the experimental methods of the surface-ship waves is introduced to lead to the experimental researches of internal waves generated by submarine Ranine ovoid in the stratified fluid.更多还原
