Abstract

With the increasing growth in computer processing power, computer based computational fluid dynamics simulations are finding increasing acceptance and use in the field of internal combustion engine development. Once fully developed, such simulations provide detailed and expedient tools for testing existing theories, as well as new ideas. While numerous studies on wave propagation and fluid flow in intakes manifolds exist, most restrict the analysis to a single intake runner and port, examining only the dynamics from the runner-to-plenum junction downstream to the valve. While such analyses provide comprehensive models for wave propagation dynamics in the runner, little is published on the fluid dynamics and wave propagation in the plenum, and the interactions between runners when an intake manifold's geometric constraints prevent symmetry in the manifold. This paper will examine the modeling of a 2003 specification Dodge Motorsports NASCAR Restrictor Plate engine using Ricardo's WAVE engine simulation computational fluid dynamics software. This examination will include an introduction to the software and required engine data for constructing a comprehensive model, the process used to validate the simulation's output with acquired engine performance data, and the use of response surface methodology to optimize the dimensions of the plenum insert associated junction. Additionally, an analysis of the problems with modeling this area of the manifold using one-dimensional CFD will be conducted, as well as a discussion of the theories surrounding the insert. Finally, a new hypothesis regarding the insert as well as future work to examine this hypothesis will be introduced.
