内部流体运动对波浪中沉井阻力的影响
Effects of inner fluid sloshing on the caisson resistance in waves
摘要
Abstract
In order to simulate the inner water flow and water exchange between the inside and the outside during the floating transportation of a caisson which is the result of the special structure of the caisson and some vertical cy-lindrical inner concavities, a simulation method has been developed. Based on the extended development of the general CFD software FLUENT, regular head wave series is numerically simulated and the resistance in the wave is computed with close attention paid to the effects of the inner fluid sloshing against the caisson resistance in the wave. The caisson resistances in 3 waves of different periods are computed with the unsteady VOF method, and the Fourier series analysis is performed to get 3 orders of harmonic amplitudes and phases. It has been discovered that the inner fluid sloshing can not be neglected, otherwise it can overcast the wave effects, and result in invalid com-putation of wave loads and caisson motions in waves.关键词
