Comparative assessment of PIV-based pressure evaluation techniques applied to a transonic base flow

A test case for PIV-based pressure evaluation techniques has been developed by constructing a simulated experiment from a ZDES simulation for an axisymmetric base flow at Mach 0.7. The test case comprises sequences of four subsequent particle images (representing multi-pulse data) as well as continuous time-resolved data. Particle images were...

Determination of instantaneous pressure in an axisymmetric base flow using time-resolved tomographic PIV

Quantification of mean and fluctuating surface loads is critical for the efficient design of aerospace structures. To measure surface pressure in experiments, wind tunnel models are typically equipped with pressure transducers, which offer high sampling rates and high sensitivity. In order to have a sufficient spatial sampling of the surface...

Determination of instantaneous pressure in a transonic base flow using four-pulse tomographic PIV

A tomographic four-pulse PIV system is used in a transonic axisymmetric base flow experiment at a nominal free stream Mach number of 0.7, with the objective to obtain flow acceleration and pressure data. The PIV system, consisting of two double-pulse lasers and twelve cameras, allows acquiring two velocity fields with time separations as small...

Experiments on a hot plume base flow interaction at Mach 2

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...

Effects of micro-ramps on a shock wave/turbulent boundary layer interaction

Stereoscopic particle image velocimetry is used to investigate the effects of micro-ramp sub-boundary layer vortex generators, on an incident shock wave/boundary layer interaction at Mach 1.84. Single- and double-row arrangements of micro-ramps are considered. The micro-ramps have a height of 20% of the unperturbed boundary layer thickness and...
