French research project NADIA incubates innovation and inter-industry partnership
LMS International continues to take the technical lead in fuel injection system simulation. A recent research project has resulted in new fluid dynamics simulation features in LMS Imagine.Lab AMESim like fluid properties for bio-diesel, implementation of CFD1D lines, and new 1D injection nozzle models.
Patrick Gastaldi, Technical Expert and Manager for Diesel Combustion Systems at Renault Powertrain Division commented, "NADIA is a great opportunity for French industrial and research partners to join forces and reinforce their competitiveness in diesel injection. This three-year public-funded program will create a real network to gather the experimental and numerical competences required to develop more efficient diesel engines. Better simulation of the entire injection system, via LMS Imagine.Lab AMESim, will be a major result of NADIA.''
Noureddine Guerrassi, Common Rail Advanced Applications Manager at Delphi Diesel Systems added, "Injection system simulation requires continuous upgrading and validation due to the permanent evolution of diesel injection technologies. With the composition complexity of the new diesel fuel, its behavior under extremely high pressure, and wide operating temperatures, enlarging the fuel characteristics library and improving injector nozzle simulation within the NADIA project can enhance the predictive potential of LMS Imagine.Lab AMESim.''
Thanks to NADIA, new LMS Imagine.Lab AMESim developments include fluid properties for various blends of bio-diesel and increasing the pressure level (up to 3000 bar) of classical diesels fluid properties. CFD1D dynamic flow piping models validated with test data were also implemented in the latest version of LMS Imagine.Lab AMESim. New injector nozzle models, developed thanks to 3D CFD and experimental results, will also permit more detailed geometric modeling and maximum accuracy concerning injector dynamics.
Within the scope of NADIA (New Advanced Diesel Injection Analysis for bio-fuels), LMS International collaborates with CD-Adapco France, Delphi, IAV France, IFP, PSA Peugeot Citroën, Renault, Total and several renowned government laboratories from France's CNRS (National Center for Scientific Research). Bringing together comprehensive, industrial diesel injection expertise, NADIA lets LMS and its partners cover all aspects of fuel injection technology from the chemical to burning soot in the combustion chamber.
