In the present study, ANSYS Fluent Computational Fluid Dynamics is utilized to analyses the non-premixed twin jet flow for propane and methanol gas mixture in a combustion chamber the process takes place in species transport and finite rate/eddy dissipation is used, and the flow assumed to turbulent and k-Ɛ realizable is occupied. The effect of changed velocities in the inlet of pipe air and jet fuel and changes of shapes of jets like circular, rectangle, triangle, star, and square on the combustion process is enhanced. the temperature and species mass fraction as well as their contours are presented. Also, the heat release rate and combustion efficiency, and equivalent ratios.

“…With the development of the computational hardware and the advancement of algorithms, the computational fluid dynamics (CFD) method has been a powerful tool to disclose the complex features in industrial applications (e.g., non-linear characteristics and streamlined curvature of the swirling flows). [13,14] Previous computational studies such as those by Wang et al [15] and Jing et al [16] analyzed the effects of swirler parameters on flow and heat transfer. The results proved that swirling flow induced by symmetrical wings can generate multiple vortices in the longitudinal direction.…”

The coaxial jet consisting of swirl jet and axial jet plays a critical role in the industrial processes but is rarely investigated; therefore, it is numerically explored by means of the computational fluid dynamics (CFD) approach in the present work. The force on the swirler, axial and tangential velocity at the annular pipe outlet, and the spatial distribution of swirl number (SN) are selected to evaluate the effect of geometrical parameters on the swirling performance. The results clarify that the velocity and their azimuthal components in the transverse cross‐section can be categorized into six segments based on high/low velocity values. The coaxial jets form a weak swirl with high axial, certain tangential, and low radial velocities. x‐ and y‐vorticity vary within −200 to 200 s−1. Coaxial jet mixing decays the SN. Based on the multi‐objective matrix analysis, swirler height has the largest effect on swirl performance followed by diameter, angle, and number based on analysis. Optimal parameters are 130° vane angle, 240 mm diameter, 10 vanes, and 250 mm height of the swirler.

“…At present, the research on single and double stage swirlers is relatively sufficient. Liu et al [5] arranged two single-stage swirlers along the flow direction, and optimized the performance of the swirler through the combination of different vane angles; Liu et al [6] carried out a numerical simulation to analyze the flow field of the dual-stage axial swirler combustion chamber, and found that the velocity distribution obtained by k-ε RNG model is more reasonable. However, due to the relatively complex geometric structure and the internal mechanism of triple swirlers, the related research is rarely reported.…”

This paper conducts a numerical study on the characteristics of mean flow field of a combustor with triple swirlers with focus on the effect of turbulence models on the central recirculation zone (CRZ). By comparing numerical results with high-speed photography experiment, it is found that k-ε RNG model can better predict the flow field characteristics than k-ε realizable and k-ω SST model. the CRZ length and expansion angle obtained by k-ε RNG model are consistent with experiments, and k-ε Realizable model are relatively close to it, while k-ω SST model is quite different from the two others. The results predicted by k-ω SST have much higher backflow strength and pressure gradient. The study is of great significance to reasonably choice turbulent mode to predict swirling flow in a combustor.
