| Abstract: | Based on MPC, a novel modular single exhaust manifold called swirl exhaust pipe system for turbocharging engines is developed. To compare the differences between the flow characteristics of both systems, the flow behavior in swirl turbocharging exhaust system is modeled by numerical approaches and is compared with that of the convenient MPC's. Numerical results show that the flow field characteristics of both manifolds are distinct. In some way the differences can explain why the two types of manifolds have different application effects. |
