Local in time solution to Kolmogorov's two-equation model of turbulence
摘要:
本文证明了具有周期边界条件的三维Kolmogorov两方程湍流模型在时间上局部解的存在性。对于适当的截断问题,我们采用Galerkin方法。接下来,我们得到了近似解的极限估计,以确保它满足原问题。
英文摘要:
We prove the existence of local in time solution to Kolmogorov's two-equation model of turbulence in three dimensional domain with periodic boundary conditions. We apply Galerkin method for appropriate truncated problem. Next, we obtain estimates for a limit of approximate solutions to ensure that it satisfies the original problem.
