Optical Coherence Tomography Velocimetry for In-Line Processing: The Spherical-to-Wormlike Micelle Transition - Data

Data for the article <i>Optical Coherence Tomography Velocimetry for In-Line Processing: </i><i>The Spherical-to-Wormlike Micelle Transition </i>by Watts Moore et al. accepted for publication in <i>ACS Engineering Au</i> in October 2025, DOI: https://doi.org/10.1021/acsengineeringau.5c00045The data is contained in four folders separated by the figure in the paper the data corresponds to.<b>Fig 3 - Linear rheology: </b>Mean amplitude and frequency sweeps at each salt concentration. Contain the strain/angular frequency, mean value of the elastic and viscous moduli (Ge, Gv) and their corresponding standard deviations.<b>Fig 4 - Nonlinear rheology: </b>Each raw file contributing to the mean shear ramp at each salt concentration. The salt concentration is denoted in the file name with an underscore in place of a decimal point. E.g. 1.1% becomes 1_1<b>Fig 5 - Velocity profiles: </b>Mean velocity profiles with the position in microns, velocity in mms^-1, standard error on the velocity, and number of individual velocity measurements contributing to the mean. The position is in a frame where 0 is at the pipe wall and the refractive index of the fluid <b>has not</b> been taken into account.<b>Fig 6,7 - Transient velocity fluctuations: </b>The transient velocity measurements at each salt concentration and flow rate. First row is the position at which the measurement was made and can be ignored. First column is the time in seconds and second column is the velocity in mms^-1.<br>
