Abstract
Computational Fluid Dynamics (CFD) has become a vital tool in the analysis and optimization of two-stroke combustion engines, enabling engineers to explore complex fluid flow, combustion, and thermal dynamics in detail. This review paper highlights the recent advancements in CFD techniques and their applications in improving the performance, efficiency, and emissions of two-stroke engines. Key areas of development include turbulence modeling, where hybrid models such as Large Eddy Simulation (LES) and Reynolds-Averaged Navier-Stokes (RANS) have been integrated to better capture the intricate flow structures and transient phenomena within the engine. Additionally, advances in multi-phase flow modeling have enhanced the simulation of fuel-air interactions, combustion processes, and exhaust scavenging, which are critical for optimizing fuel efficiency and minimizing emissions. The paper also discusses the role of hybrid models that combine LES and RANS to balance computational cost and accuracy, and highlights recent innovations in CFD tools and solvers, which have made simulations more accessible and efficient. The use of these advanced CFD techniques has significantly improved the understanding of two-stroke engine behavior, enabled more effective design modifications and contributed to the development of cleaner, more efficient engines. This review underscores the importance of CFD in advancing two-stroke engine technology and addressing future challenges in engine design and environmental sustainability
