The dataset includes unprocessed and processed temperature evolution plots for wide range of experimental conditions corresponding to ice crystal icing performed at the icing wind tunnel of TU Braunschweig within the scope of MUSIC-haic project. In addition to temperature plots the dataset also includes information on the design and components of the test article as well as the respective test matrix. It covers wide range of parametric variation including heat flux, wet bulb temperature, flow velocity and ice water content and provides a sound basis for calibration and validation of numerical tools.
