LARGE EDDY SIMULATION OF FULLY TURBULENT CHANNEL FLOW USING VARIATIONAL MULTISCALE METHOD
변분다중스케일법을 이용한 $Re_{\tau}=180$ 채널 난류 유동의 대와류모사
Abstract
In the present work, LES with new variational multiscale method is conducted on the fully developed channel flow with Reynolds number is 180 based on the friction velocity and the channel half width. Incompressible Navier-Stokes equations are integrated using finite element method with the basis function of NURBS. To solve space-time equations, Newton's method with two stage predictor multicorretor algorithm is employed. The code is parallelized using MPI. The computational domain is a rectangular box of size
