Abstract:
Flow and heat transfer performances of the tubes with internal longitudinal plat-rectangle fins in exhaust gas recirculation(EGR)cooler were investigated by three-dimensional computation and experiment. The effects of the upward wind distance of the internal fins on tube-side heat transfer performances were examined by a numerical method. The research results showed that the novel internally finned tube could enhance heat transfer characteristics, the maximum deviations between numerical results and the experimental data were approximately 6.7% for pressure drop, 6.5% for friction factor and 5.9% for Nusselt number, and the longer the upward wind distance, the better the hear performances.
