　　FFTW is an open source library widely used in numerical simulation of turbulence to accelerate the computation.Under most conditions,the option used in FFTW can only influence the computation speed but has no effects on the results.However,since turbulence is a chaos system,any slight numerical differences will be amplified if simulation time is long enough.

粘弹性流体圆柱绕流流噪声数值模拟研究

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

除尘管道粉尘运移及沉积研究

采用欧拉–拉格朗日方法，并考虑气相与颗粒相的双向耦合，对管道内不同工况下气固多相流动进行了数值模拟。基于颗粒与壁面碰撞过程中的能量分析，建立了粉尘沉积–回弹模型，即粉尘颗粒与壁面碰撞后，法向速度所对应的动能大于壁面的黏附能才会回弹，否则会被壁面捕获。由此得出了粉尘颗粒的沉积准则以及颗粒碰撞后的回弹速度。
