AI Article Synopsis
- * It examines the effectiveness of a 3-lobe annular nozzle and the use of internal air jet flows to enhance fuel mixing behind a strut.
- * Numerical simulations demonstrate that the annular 3-lobe design creates multiple vortex pairs, significantly boosting fuel mixing efficiency to 90% in the scramjet combustor.
Article Abstract
The role of efficient fuel mixing and a stable flame holder is crucial in enhancing the performance and capabilities of scramjet engines for high-speed flight. The present research paper has tried to disclose the fuel mixing efficiency of 3-lobe annular nozzle on the mixing mechanism of the fuel jet behind the strut. In addition, using internal air jet flow for increasing the circulation strength and fuel mixing behind the strut is also examined in this study. Numerical simulation of the flow and fuel jet behind the strut is done to reveal the main physics related to the mechanism of fuel mixing inside the combustor with the proposed injection system. The results of our simulation show that using annular 3-lobe fuel jet improve the fuel mixing via production of the multiple vortex pairs within the combustor behind the strut. The use of internal air jet also enhances the fuel mixing efficiency up to 90% in combustor of scramjet engine.
