1 lip 2019 · Abstract. Large Eddy Simulations (LES) in conjunction with the Flamelet Progress Variable (FPV) approach have been performed to investigate the flame and large-scale flow structures in the bluff-body stabilized non-premixed flames, HM1 and HM3.
10 sty 2014 · In the present work, the effect of bluff body shape on the blow-off limit was investigated with a detailed H 2 /air reaction mechanism. The results show that the blow-off limits for the triangular and semicircular bluff bodies are 36 and 43 m/s respectively at the same equivalence ratio of 0.5.
10 cze 2021 · PDF | This review investigates the nature-inspired techniques for the optimization of the aerodynamic forces on bluff bodies.
1 cze 2014 · Highlights. •. The maximum flame temperature occurs when wall-blade was applied as a bluff body. •. Apart from wall blade, the maximum flame temperature was recorded at V2 = 20 m/s for all cases. •. When inlet velocity of mixture increases from 20 m/s to 30 m/s, the flame temperature reduces in all studied cases. •.
The optimal spanwise spacing between the adjacent tabs is sim-ilar to that in Darekar & Sherwin (2001). However, for three-dimensional blu® bodies such as the sphere or some transportation vehicles, the vortical struc-tures are essentially three dimensional (Yun et al., 2006).
18 wrz 2020 · The timescale and evolution for erosion along a range of bluff types found along the shoreline of Lake Michigan can be analyzed in response to this ubiquitous rise in water level. This common forcing factor allows for comparison of other factors that control bluff stability and evolution. Figure 1.
Bluff Body Aerodynamics. Richard G.J. Flay. n understanding wind engineering. Streamlined bodies like aircraft wings have a rounded nose, a thin p. ofile, and a sharp trailing edge. Their wakes are small and for small angles of attack, the lift force developed is conside.
