Abstract:

Oil and gas flow from the Macondo255 wellhead were simulated using a large eddy simulation (LES) approach. This dataset includes the simulated oil and gas holdups (both along the radial and centerline direction), flow velocity, turbulence dissipation rate, and entrainment coefficient. The data was generated by CFD-LES approach using FLUENT software and post-processed by TECPLOT and Excel.

Methods:

lpk raw data files can be opened by TECPLOT software. For decoding conventions, open the lpk file, click "write data" in the main menu, and an ASCII file can be written.
