Data for publication: Numerical analysis of influence of various bluff-body shapes on diffusion flame dynamics

Research data related to the publication "Numerical analysis of influence of various bluff-body shapes on diffusion flame dynamics". In this paper, we investigate various bluff-body shapes (cylindrical, square, star) and two different surface topologies (smooth, wavy) as passive tool to control a non-premixed hydrogen flame in a combustion chamber. Employing large-eddy simulations (LES) with ANSYS Fluent and the academic code SAILOR, we analyze flame dynamics near the injection system and in the far field. The results reveal that bluff-body shape significantly impacts flame behavior. Square and star shapes enhance combustion through interactions between vortices of various sizes. Smaller vortices generated at the corners deform large-scale structures, affecting mixing and resulting in a more uniform temperature distribution.The research was carried out as part of project No. 2020/39/B/ST8/02802, financed by the National Science Centre (Poland).The readme file contains sorted filenames linked to the figures from the article.For details on file formats please refer to the readme file and documentation: https://www.tecplot.com/2016/09/16/tecplot-data-file-types-dat-plt-szplt/
