SUMMARY OR ABSTRACT
Text of Note
Engine operation, pollutant formation and fuel consumption in diesel engine, beside injection rate, is influenced by spray atomization and air/fuel mixture formation. The experimental studies show that cavitation phenomenon inside the injector nozzle, determines the specifications of outlet spray and fuel atomization. In this study, the AVL Fire code is used to investigate a 3D, two-phase, transient model of cavitation inside nozzle. The typical geometry for representing a fuel injector nozzle has L/D of about 5 and a sharp inlet corner. The injection pressure is varied from 10MPa to 160MPa. For study the effect of nozzle geometry on cavitation the results are presented for a range of L/D from 2.5 to 10. Similarly, results for a range of rounded inlets from 0.01mm to 0.05mm are presented. Models are designed by SolidWorks, and then the surface mesh is created by ICEM to transport the model to Fire. At last, the basic equations are solved by Fire solver to predict the flow inside the injector nozzle.
