One-dimensional and Three-dimensional Modeling of Dynamic Fluid Flows in a Four-stroke Multi-cylinder Spark-ignition Engine

This project’s focus is high-performance engine design for the Formula SEA collegiate design competitions. Computer models are developed to simulate the complex fluid flows found within air-restricted, high-performance combustion engines. These simulation results are used in component design studies to optimize engine volumetric efficiency. Engine fluid flows are simulated with Ricardo Software’s WAVE 1D and VECTIS 3D engine flow modeling programs.

Current work focuses on optimization of intake manifold shape and physical dimensions based the group's previous published results. Intake models will be constructed and cylinder-to-cylinder volumetric efficiencies will be compared with the use of an engine dynamometer. Dynamometer performance data will also be compared to software performance predictions.
