• The characteristics of the shock wave propagation through an array of cylinders perpendicular to the flow are experimentally investigated by using the shock tube. Quantitative and qualitative infornra-tion on the attenuation of the transmitted shock wave, the pressure augmentation due to the reflected shock wave and the pressure oscillation in the wake due to shedding of the K~rman vortices is obtained from the unsteady pressure measurement. The schlieren pictures reveal the flow patterns of these features. Various cylinder arrangements are tested and their effects are discussed. The essential features of the propagation process are successfully simulated by the unsteady one-dimensional Euler analysis considering the drag force produced by the cylinder array. The drag force is evaluated by fitting the numerical results to the experimental data.
