1 - Objectives

Tester la testabilité de rotation de la plate-forme Coriolis pour différentes conditions de rotation.

.

2 - Experimental setup

2.1 General description

La plate-forme Coriolis a été mise en rotation suivant différentes conformations (cf. 2.4) afin d’évaluer la stabilité du fluide (eau) lors des rotations.

Deux cameras (Dalsa1 et Dalsa2), positionnées 5,27m du centre et séparées de 1,40m (cf. 2.2), ont enregistré 4000 images lors de chaque essai pour permettre une étude précise des déplacements de particules dans l'eau.

4 - Methods of calibration and data processing:

5 - Organization of data files:

All data related to the project are in Coriolis /.fsnet/project/coriolis/2014/'project name'

  • 0_DOC: miscellaneous documentation and reports
  • 0_MATLAB_FCT: specific matlab functions
  • 0_PHOTOS: photos of set-up
  • 0_REF_FILES: files of general use (calibration data, grids ...)
  • 0_RESULTS: processed data (time series, statistics...) and figures.
  • EXP1, EXP2, folder for each experiment. Structure of each Experiment folder:
    • DeviceFolder: corresponding to the data of a given instrument or camera.
    • Results from data processing are stored in a folder DeviceFolder.ext where ext is set by the processing program.
    • An xml file named DeviceFolder.xml specifies information from the devices, for instance timing and calibration parameters for an image series.

6 - Table of experiments
