【摘要】

：

向水中添加可溶性高分子聚合物可以得到粘弹性流体。本文通过商用软件Fluent 的UDF 二次开发功能对粘弹性流体流经雷诺数100 的圆柱绕流进行二维数值模拟，并将流场仿真的结果进行声类比计算了流致噪声。粘弹性流体的本构方程选用FENE_P(L2=10000)模型，流场计算的结果与已有文献进行对比，吻合较好。数值模拟的结果表明，水溶性高分子聚合物的添加可以起到抑制流场噪声的效果，包括近场噪声和远场噪

自由单元配点法及其在CFD中的应用

工程中常用的数值方法是有限单元法(FEM)和有限体积法(FVM)，它们分别在计算固体力学和计算流体力学领域得到了广泛的应用。然而，建立有限元法计算格式需要变分原理或能量原理，对于不同的问题所用的表达形式不同，不便于建立多场耦合问题的统一求解格式。

基于重叠网格技术的双折角滑行艇阻力数值预报与验证

本文针对双折角双防溅条滑行艇，基于RANS 方程，采用重叠网格技术，对滑行艇静水直航状态下的阻力及航行姿态进行预报，解决了传统运动域方法因流域随船体运动而导致自由液面倾斜失真的问题，并将计算结果与模型试验数据进行了对比，结果表明阻力及运动姿态与试验数据吻合较好，证实了文中数值模拟方法应用于高速滑行艇自由模拖曳航行数值预报的可行性。
