A HYBRID TURBULENCE MODEL FOR WAVE BREAKING SIMULATION

Department of Applied Mechanics and Engineering, Sun Yat-sen University, Guangzhou 510275,China

摘要

摘要: 近岸波浪的变形与破碎,一方面影响水体标识码运输,另一方面对消波护岸具有指导意义.本文提出一种三维混合湍流模拟模式方法,将求解区域分为造波区、波浪传播区和消波区. 造波区采用层流模式,通过基于 Fluent 的二次开发的 UDF 方法在边界进行速度造波.这种方法在给定入口速度的条件标识码据已知波高进行精准插值,从而控制水的体积分数. 在波浪传播区域,采用大涡标识码行模拟研究,在消波区,采用 RANS 模型并利用多孔介质消波法进行消波. 模标识码 VOF 方法捕捉波浪破碎过程中的自由面变化.本文对波高为 5.5cm 的规则波 (M1)、波高为 13.5cm 的规则波 (M3)、有效标识码 7.75cm 的 TMA 谱单向不规则波 (U1) 和有效波高为 19cm 的 TMA 谱多向不规则波 (B5) 展开标识码研究,并与前人的相关标识码果作比较,各条件下模拟结果与实验结果吻合.模拟结果说明本文提出的模型能够准确模拟出波浪传播过程中的折射和标识码象,并且能够捕捉的波浪破碎过程中的自由面变化,为三维波浪的传播与破碎的数值模拟提供一种模拟方法.

Abstract: On the one hand, the deformation and breaking of near-shore waves affect the transportation of water and sediment, and on the other hand, it is of guiding significance for wave elimination and revetment. In this paper, a 3-dimensional hybrid turbulence simulation model is proposed. Laminar flow mode is adopted in the wave-making region, and velocity wave-making is carried out at the boundary through the User Defined Function(UDF) developed based on fluent. This method can control the volume fraction of water by precise interpolation according to the known wave height under the condition of given inlet velocity. In the wave propagation region, large eddy simulation (LES) is used for simulation research, and in the wave elimination region, RANS model with the porous media wave absorber is used for wave elimination. The model uses the VOF method to capture the free surface changes in the process of wave breaking. This paper carried out simulation studies on the regular wave (M1) with a wave height of 5.5cm, the regular wave (M3) with a wave height of 13.5cm, the unidirectional irregular wave (U1) with a TMA spectrum with an effective wave height of 7.75cm and the multidirectional irregular wave (B5) with an effective wave height of 19cm. Simulation results show that the proposed model can accurately simulate the wave propagation in the process of refraction and diffraction phenomenon, and be able to catch the waves of the free surface in the process of change, broken for 3D wave propagation and broken numerical simulation provides a method of simulation.
