中文摘要 | numerical simulations of freak wave generation are studied in random oceanic sea states described by jonswap spectrum. the evolution of initial random wave trains is numerically carried out within the framework of the modified four-order nonlinear schroedinger equation (mnlse), and some involved influence factors are also discussed. results show that if the sideband instability is satisfied, a random wave train may evolve into a freak wave train, and simultaneously the setting of the phillips parameter and enhancement coefficient of jonswap spectrum and initial random phases is very important for the formation of freak waves. the way to increase the generation efficiency of freak waves though changing the involved parameters is also presented. |
