摘要
本文在分析了针对充分发展湍流模型建立的k方程湍流模型模拟转捩流动的能力之后,构筑了一种新的Fμ函数及相应的k方程湍流模型.将该模型应用于数值求解NS方程,模拟了中等来流湍流度下零压力梯度平板捩报流动,并将部分计算结果与实验结果及经验关系进行了比较.
By using a new function Fμ, which is constructed elaborately to include more physicalcharacteristics of transition phenomena, a new k-equation turbulence model is proposed inthis paper. Coupling with the present model, numerical tests of 2D NS solver on flat plateflow with zero pressure gradient are carried out to identify its capability of transitional flowmodeling.
