<div class="section abstract"><div class="htmlview paragraph">The thermoelectric generator system is regarded as an advanced technology for recovering waste heat from automotive exhaust. To address the issue of uneven temperature distribution within exchanger that limits output performance system, this study designs a novel generation integrated with turbulence enhancers. This configuration aims to enhance convective transfer at rear end and improve overall uniformity. A multiphysics coupled model established evaluate impact enhancers on system's electrical output, comparing its traditional systems. The findings indicate integration significantly increases rate uniformity exchanger. However, it also leads increase in exhaust back pressure, which negatively affects performance. At lower flow velocities, gains power attributable considerably outweigh pressure. Specifically, under conditions 550 K 20 m/s, power, net coefficient by 39.2%, 33.6%, 8.5%, respectively. As rises, become even more pronounced. Nevertheless, high conditions, rise pressure can potentially degrade Therefore, recommended be appropriately diverted practical applications ensure optimal research provides essential theoretical guidance design optimization systems.</div></div>
