基于光滑粒子流体动力学的海浪建模研究
he ocean wave model construction based on smooth particle hydrodynamics
海浪是一个十分复杂的自然现象,其形态在运动过程中是动态变化的,而且具有复杂的动力学、光学、时空等特性。模拟风浪场,首先就要对海浪进行建模,它在很大程度上决定了仿真效果的优劣。本文基于光滑粒子流体动力学(SPH)方法的流体模拟算法以及海浪粒子与障碍物的碰撞检测算法,建立海浪运动模型完成微观尺度下海浪的运动以及对海上或海岸物体的冲击模拟。该方法是对基于粒子系统与物理模型的流体模拟方法的一种延伸,它可避免欧拉方法中出现的一系列问题,而且在粒子数不大时,可实现海浪的实时仿真效果。
he wave is a very complex natural phenomenon, its shape is dynamic in the process of movement, but also has dynamics, optics, spatial and temporal characteristics of complex. Simulation of wind field, the first thing is to carry on modeling to the waves, which determines the simulation effect to a great extent. In this paper, based on the smoothed particle hydrodynamics (SPH) method ,the fluid simulation algorithm and wave particle collision and obstacle detection algorithm, the establishment of the wave motion model to complete the movement of micro scale of waves and offshore or onshore object impact simulation. The method is an extension of simulation method of fluid particle system and based on physical model, it can avoid a series of problems in Euler method, but also in the number of particles is small, can realize real-time simulation effect of the waves.
