The paper presents the cold flow measurements in a two-dimensional dump diffuser. The laser Doppler velocimeter was used for the measurements of mean velocity components and its fluctuation in order to clarify the flow regimes in a sudden expansion region. Wall friction velocity on the outer wall wa...
