Velocity Vector Data from PIV Measurements of Bass Recorder Interior under Normal Playing Conditions

This dataset includes two types of measurements:1) Full length measurement spanning the whole length of the transparent bore of the bass recorder comprised of multiple measurements that can be tiled to obtain full length measurement. This set of measurements features a naming scheme:Ux*** - horizontal velocity vectorsUy*** - vertical velocity vectors **F** - first tone hole position (in the paper referred to as x_1)**L** - last tone hole position (in the paper referred to as x_2) ***12 - tone hole diameter in millimetres These files are python 'dict' type objects. Example case structure of horizontal velocity vector for the case of 9 mm tone hole at the tone hole position p_2:Filename: 'UxF09.mat'Type: dictDictionary keys: '0', '1', '2', '3', '4', '5', '6', '7' 2) Local flow velocity measurement under the tone hole position x_1. This set of measurements features a naming scheme:UxZoomed_* - horizontal velocity vectorsUyZoomed_* - vertical velocity vectors U*Zoomed_D - non-undercut tone hole casesU*Zoomed_U - undercut tone hole cases These files are python 'dict' type objects.
