Oscillatory Turbulent Boundary Layer Flow By
Control-volume Approach
Author(s)
S. Tigrek & Masahiko Isobe
Abstract
A general numerical method for the solution of the complete Reynolds-averaged
Navier-Stokes equations for ID and 2D oscillatory flow is described. The
method uses orthogonal/nonorthogonal co-ordinates, contravariant and covariant
velocity components and a pressure-velocity-coupling algorithm for staggered
grid system. The capability of method and the overall performance of the k-e
model are demonstrated by calculations of flow over flat and rippled beds.
Numerical tools that will be required for a robust code are examined.
1 Introduction
Oscillatory flows can be observed in both manmade and natural
environment. For example, in the nature, oscillatory turbulent boundary
layer develops over the sea bottom as the surface waves approach to the
shore. When the interaction
