For the particular case studied in this article, the two-dimensional simplification is justified as the results did not vary notably whereas entailing remarkably smaller computational costs. Nonetheless, the usage of DES turbulence model yielded moderately different results, qualitatively closer to deposit observations, justifying perhaps the three-dimensional approach when accuracy is needed for the deposition of fine particles on the lee edges of the tubes.
