Flow characteristics of a two-dimensional jet with curved side walls have been studied experimentally. Four kinds of cylindrical walls were provided as the side walls, and they were combined and attached to a nozzle. Velocity was measured by a hot-wire probe. Mean velocity profiles, the decay of jet maximum velocity, and the growth of the jet half-width were clarified. The maximum velocity decays as the radius of the smaller cylindrical wall becomes large. When the radius of the smaller cylindrical wall exceeds a certain radius, the jet half-width increases suddenly.
