Optical measurement of the shear stress and velocity distribution in an idealized deglutition process


Optical measurement of the shear stress and velocity distribution in an idealized deglutition process

Skrypnik, A.; Heitkam, S.; Gerstenberg, C.; Morelle, E.; McHardy, C.; Rauh, C.

The paper and dataset on the modelling of foam deglutition in a replica of a human mouth cavity.
It includes the optical measurement of elastic stresses and bubble flows of the foam flow furing the deglutition.

Each data folder includes:

Laborbuch.xls labbook
Fluessigkeitsgehalt--data on liquid fraction

1. masking2.mlx script --- script to create the mask for the tongue and palete plates
2.025 --- original data folder
3.025_pre --- cutted (to ROI) image data folder
4.025_pre_predict --- folder with the ANN processed data, with enhanced bubble positions
5.masked2--- masked images
6.SCRIPTS--- folder with the matlab scripts
6.* some video for the visualisation
7. Calculate_new-- folder with the scripts used for the calculation. Including:
common_mod.msx --- common matlab file for the stress data at the right wall
left_common_mod.msx --- common matlab file for the stress data at the left wall
tau_loc_left.m -- to plot the graph
all_script.msx --- run the common file for all the images

bub_parts -- folder with the files to define bubble velocity:

full_bub-- velocity of full bubble

Keywords: foam; deglutition; shear stress; bubble tracking
