Numerical results for hydrogen flames stabilized by bluff bodies: flow dynamics downstream of bluff bodies with inclined upper surfaces

Research data related to the publication "LES of flow dynamics downstream of bluff bodies with inclined upper surfaces".

This dataset contains numerical simulation results of non-reactive flow past cylindrical bluff bodies with different upper surface shapes: flat, concave, and convex. A fuel jet is injected at the center of the bluff body, while the oxidizer flows through an annular duct surrounding it. The primary focus of the study is on the mixing process and the influence of the bluff body surface shape on downstream flow behavior.

The simulations were conducted using the Large Eddy Simulation (LES) method with two different solvers:

• The commercial code ANSYS Fluent
• The in-house high-order code SAILOR

The simulation results are provided in files named Fig*.dat, where each file corresponds to a figure from the associated publication. The readme.txt file includes a sorted list of filenames linked to the respective figures.
