This is the dataset for the Axisymmetric body (0.16m diameter, elliptical nose cone, l/d = 5), collated by Max Varney (https://www.linkedin.com/in/max-varney/) on 2020/06/15. More information for the geometry and analysis using dataset #1 can be found in the paper "Three dimensional structure of the unsteady wake of an axisymmetric body", Physics of Fluids 31, 025113 (2019); https://doi.org/10.1063/1.5078379. The paper is also available on the Loughbrough University research repository at: https://hdl.handle.net/2134/37058

Data was collected in the Large Wind Tunnel at Loughborough University, a 2.5m^2, closed working section, fixed ground open return tunnel. Details of the tunnel can be found in: https://hdl.handle.net/2134/6674

The CAD geometry for the wind tunnel and the axisymmetric body with its mounting are included in the dataset as ASCII .stl files, with the units in meters. Note: at the start of every experiment the yaw and pitch of the model was incrementally adjusted to produce a symmetric base pressure.

All data is presented in SI units and all measurements are from the origin of the model (on the base of the model, at the centre of the base) with x positive downstream and z positive up, using a right hand rule to find positive y.

There are two datasets.
DATASET #1 - 30m/s (Re_d=3.2x10^5)
Contains: Tomographic Particle Image Velocimetry and Base Pressures

DATASET #2 - 40m/s (Re_d=4.3x10^5)
Contains: Planar (Y=0m, Z=0m and Z=0.04m) and Stereo (X=0.06m, X=0.12m, X=0.18m and X=0.24m) Particle Image Velocimetry, Base Pressures and Forces
