抄録

For the purpose of studying the finite element method in high-Reynolds number turbulent flow, we apply the finite element method with tetrahedra bubble-function element and large eddy simulation(LES). In order to show the workability and the validity of the present schemes, the channel flow is demonstrated as turbulent flow at Reynolds number = 180. The numerical results are compared with the DNS data by Kim et al.
