The present study concerns with the flow around two-dimensional cosine-shaped single hill. The set of experimental results obtained from a simulation performed in a boundary layer wind tunnel includes the mean and fluctuating velocity profiles as well as surface pressure distribution over the model hill. The visualisation technique is also used to find the rccirculation zone and reattachment point in flow considered.
