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: 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 ...
