在使用尺度解析模拟(SAS、DES、SDES、SBES和LES模型)时,可以指定速度和压力入口处的非稳态 Fluctuating Velocity ,以生成真实的湍流内容。因此,对于速度和压力入口,需要额外的输入,例如选择 Fluctuating Velocity Algorithm 及其相应参数(如图7.34所示)。在Fluent理论指南中的尺度解析模拟入口边界

ii. Retain the default No Perturbations in the Fluctuating Velocity Algorithm drop-down list, and click OK.. This tutorial does not make use of FLUENT ’s ability to impose inlet pertur- bations at velocity inlets when using LES. It is assumed that all unsteadiness is due to the presence ...

The physics behind the Helmholtz resonator is similar to wind noise applications like sun roof buffeting.We assume that out of the two cavities that are present,smaller one is the resonator.The motion of thefluid takes place because of the inlet velocity of27.78m/s(100km/h).The fl...
