Using 1-D and 3-D Models for the Simulation of Gas Exchange Processes

It has been developed a comprehensive tool to simulate the Gas Exchange process in two and four stroke engines. By using jointly unidimensional and tridimensional models, it can be possible to use the adequate tool in every part of the whole control volume. Using empirical coefficients, matched with both models, the same results are obtained in a test case, using in the first place the unidimensional model and in the second place the tridimensional model. In this way, the complete process can be calculated in a reasonable short time and without experimental results to know empirical constants.
