Data analysis and performance model calibration of a small turbojet engine
Bakalis, D. P.; Stamatis, A. G. (2012)The experience gained during the development of a small turbojet engine simulation model is presented in this article. The calibration of an initial model has been proven inadequate for producing reasonable values for some ... -
Exergy analysis of a hybrid micro gas turbine fuel cell system based on existing components
Bakalis, D. P.; Stamatis, A. G. (2012)A hybrid system based on an existing recuperated micro-turbine and a pre-commercially available high temperature tubular solid oxide fuel cell is modeled in order to study its performance. Individual models are developed ... -
Extended instrumentation and model calibration for a small micro-turbine
Bakalis, D. P.; Stamatis, A. G. (2010)In this paper the calibration of a model representing a real small turbojet engine is presented. The development of the model was based on a modular general approach using adaptive modeling principles. Calibration of the ... -
