【摘要】 基于现代流体力学的有限体积高精度模拟方法,提出了一维河道水流模拟的高精度离散方法,针对有限体积法边界处理问题,提出了一种能保持全局守恒且具有较强物理意义的处理模式,提高了模拟方法的稳定性和精度。通过几个流体力学经典算例验证,表明本文提出的方法具有较好的效果。更多还原

【Abstract】 A high resolution numerical method was introduced based on finite volume of computational fluid.In order to deal with the boundary,a new method was recommended,which can keep global discharge conservative,improve the stability and the accuracy.The present numerical method was applied to two different benchmark problems,both reflected that the introduced method was confirmed to he effective.更多还原
