Supervision of a counting system of the natural gas of a thermal power plant

  After a presentation of the functionality of a supervisory system for complex processes, we present the concepts of a supervisory control and data acquisition(SCADA) system. An application of supervision of a counting system of the natural gas (NG) of a thermal power plant (TPP) in Tunisia was realized. The paper briefly discusses the different steps of this application and some advantages of SCADA...

Turbulence study in the internal combustion engine

  In this paper, we are interested in the study of turbulent and time dependant flow inside a cylinder of an alternative engine through the investigation of the distribution of the turbulent kinetic energy in the whole space of the chamber. This research is carried out during the intake stroke. The arbitrary lagrangian eulerian technique coupled with the finite element method is used to solve the Navier Stokes...
