Entropy Generation of Flow Restriction: Modeling and Identification
2000 (English)In: Proceedings of the 2000 SAE World Congress, 2000Conference paper (Refereed)
An alternative method to modeling and identification of flow restrictions built-in the IC engine air-flow system has been proposed. It is based on modeling of flow losses, i.e the entropy change avoiding detailed geometry modeling.
It allows to generate the integrated model of flow restriction covering all operating modes in one equation and, to some extent, to predict the temperature ratio over the flow restriction.
A modified version of the model has been elaborated to achieve the computational stability. The model has been verified using the experimental data from SAAB'95 production engine throttle plate.
