摘要
针对轮式两栖车辆水上航行快速性问题,基于FLUENT平台并利用k-ε湍流模型和VOF两相流模型对两栖车辆绕流场进行了数值模拟,得到了轮式两栖车辆航行阻力的变化规律.通过与拖模试验结果对比分析,二者结果基本吻合,论证了数值模拟方法的正确性,符合排水型两栖车辆的阻力规律,为轮式两栖车辆的结构优化及减阻增速研究提供了参考依据.
In view of the speed of the wheeled amphibious vehicle shipping on the water, numerical simulation of flow field was presented, making use of k-e turbulent model and VOF two-phase flow model based on the Fluent platform, the sailing resistance variation of the amphibious vehicle was got. By comparison with the result of model of dragging experiment, the result of numerical simulation is confirmed, which is in line with the law of the resistance of drainage amphibious vehicles, and provides the reference for the structural optimization, resistance reduction and speed increasement of wheeled amphibious vehicles.
