Abstract：There exist several theories about the vertical profile of wave radiation stress,and the verification of these theories is seldom done.In the present paper,an idealized numerical wave flume is established based on Computational Fluid Dynamics (CFD) software FLUENT,upon which the linear waves are simulated.The results show that the proposed numerical wave tank is effective in simulation.The vertical structure of wave radiation stress is studied and it is concluded that the radiation stress in surface experiences a dramatic change due to wave action.It is shown that the integration of radiation stress in surface region is discontinuous with that within fluid.The validity of the above-mentioned theories is tested in experiments with different incident waves on the basis of linear wave theory.The comparison between numerical outcome and theoretical ones is conducted and it is shown that the validity of theories depends on both wave type and calculation region.
