Experiments were performed to determine the mean velocity field in two three-dimensional (3D) diffusers with the same fully-developed channel inlet but slightly different expansion geometries. Magnetic resonance velocimetry was used to collect velocity data. Both diffuser flows exhibited 3D boundary layer separation but the size and shape of the separation bubble exhibited a high degree of geometric sensitivity dependent on the dimensions of the diffuser.
