In order to verify the validity of the kinematic simulation methods, the turbulent field around two-dimensional symmetric aerofoil in the grid turbulence has been measured and compared with the simulation results. The model used in this study is the combined model of random Fourier modes method and Rapid Distortion Theory (RDT). For two cases of τ_<max>/L_E (τ_<max>: maximum aerofoil thickness; L_E: the integral length scale of incident turbulence), the effect of the blocking and distortion on the wavenumber spectra and the r.m.s. velocity fluctuation have been mainly investigated. As a whole, the simulation results show good agreements with the experimental results, so the validity of the present kinematic simulation is confirmed.
