Paper Number: ISOPE-I-21-3149
... Abstract Detection of free surface waves signature induced by submarine in the stratified environment has been a canonical question. In this paper, we investigate the main body aspect ratio of a generic submarine effect on the free surface waves using RANS simulation. The slenderness ratios L...
