A wind tunnel model containing a solid rocket motor was tested at Mach 2 to assess the feasibility of investigating the interaction between a hot plume and a high-speed outer stream. In addition to Schlieren visualisation, the feasibility of applying PIV was explored. Recorded particle images revealed that the hot plume scatters and reflects laser light, leading to a strong deterioration of the illumination conditions in regions within and near the plume. Suitable processing of the particle images could partly compensate for this and reliable velocity measurements could be obtained in directly illuminated regions. In regions near the base and below the plume, velocity measurements could still be obtained but were considered to be of lower quality. No reliable velocity measurements could be obtained within the plume itself.
