I am actually working as a consultant at Peugeot Citroen France as a Fuel consumption and Emissions expert on Future Diesel Engines (2020).

The aim of my work is to build a combustion and emission models suitable for Hardware in the Loop (HiL) simulations, and thus to be able to run in Real-Time applications. First, an ignition model is presented and correlated function of engine operating conditions. Then the combustion and emission models parameters were calibrated with a curve fitting technique with test bench experimental results. The calibration and validation process have been realized first on Matlab. Then the combustion model was coded in S-functions Simulink blocks suitable for HiL implementation.

the work is the study of the surge in the centrifugal compressors using the model of greitzer.
this model was implemented in a 1 D simulation code and then a lot of experimental data was done to validate it using GT Power
