GitLab now enforces expiry dates on tokens that originally had no set expiration date. Those tokens were given an expiration date of one year later. Please review your personal access tokens, project access tokens, and group access tokens to ensure you are aware of upcoming expirations. Administrators of GitLab can find more information on how to identify and mitigate interruption in our documentation.
Here are the codes: diffusion2D_comp_article.ipynb in the main repository and diffusion2D.ipynb in the 'augmentation_debit', 'augmentation_freq' and 'osc_default' folders
Here are the codes:
-**diffusion2D_comp_article.ipynb** in the main repository
-**diffusion2D.ipynb** in the 'augmentation_debit', 'augmentation_freq' and 'osc_default' folders
## Description:
In each folder, the code diffusion2D.ipynb is undertaking the numerical solving of the diffusion equation of overpressures due to an exploitation with an oscillating flow rate. Each folder corresponds to a study case:
1. for 'augmentation_debit', a monopole with a oscillating flow rate of 240 m^3/h
2. for 'augmentation_freq', a monopole with a oscillating flow rate with a frequency of 1/12 1/h.
3. for 'osc_default', a monopole with a oscillating flow rate of 120 m^3/h with a frequency of 1/24 1/h.
## Outputs:
Description: In each folder, the code diffusion2D.ipynb is undertaking the numerical solving of the diffusion equation of overpressures due to an exploitation with an oscillating flow rate. Each folder corresponds to a study case: (i) for 'augmentation_debit', a monopole with a oscillating flow rate of 240 m^3/h ; (ii) for 'augmentation_freq', a monopole with a oscillating flow rate with a frequency of 1/12 1/h. and (iii) for 'osc_default', a monopole with a oscillating flow rate of 120 m^3/h with a frequency of 1/24 1/h. For each code, we have the Following outputs:
For each solving of the diffusion equation there are the outputs saved in the 'save_profiles' subfolder:
(i) Data files named 'Pt_xxm_inj_cst.dat' of different temporal (time in hours in 1st column) evolution of overpressures (in bars in 2nd column) for injection with an oscillating flow rate. Here xx is equal to different tested set (x,y) coordinates: {xx=200m for {200m,200m} ; xx=500m for {500m,500m} ; xx=1km for {1km,1km} ; xx=2km for {2km,2km} ; xx=4km for {4km,4km} ; xx=6km for {6km,6km} and xx=8km for {8km,8km}}.
(ii) Data files named 'Px_xxm_inj_cst.dat' of spatial profiles (distance in km in 1st column) of overpressures (in bars in 2nd column) for injection with an oscillating flow rate. Here xx is equal to different tested set y-coordinate: {xx=200m for {200m,200m} ; xx=500m for {500m,500m} ; xx=1km for {1km,1km} ; xx=2km for {2km,2km} ; xx=4km for {4km,4km} ; xx=6km for {6km,6km} and xx=8km for {8km,8km}}.
