Abstract: Frequency-dependent friction can be an important dissipative factor for unsteady flows. In this research investigation, various popular models have been reviewed thoroughly and then applied to evaluate frequency-dependent ...

Abstract: A compressible flow with wall friction has been predicted in a constant cross section duct by means of a barotropic modeling approach, and new analytical formulas have been proposed that also allow any possible heat transfer ...

Abstract: Exhaust gas recirculation (EGR) is extensively employed in diesel combustion engines to achieve nitrogen oxides emission targets. The EGR is often cooled in order to increase the effectiveness of the strategy, even though ...

Abstract: The innovative common feeding (CF) fuel injection system has been designed for a light duty commercial vehicle diesel engine in order to reduce production costs and to allow easy installation on the engine, compared with ...
