“…In this figure is also presented that, for all cases, the shear stress produced by the effect of viscosity around the orifice walls is more significant at the inlet of the orifice than at its outlet. Similar result was observed in Salvador et al 42 However, results obtained in the present work are twice in order of magnitude for all operating engine modes and fuels than those presented in the cited reference.…”

“…In this sense, 1D modelling appears to be an appropriate solution, since it may provide a deep insight on the complete injection process at a low computational cost compared to computationally expensive 3D CFD simulations usually restricted to a specific part of the injector [12][13][14] or to spray development [15]. In fact, the 1D modelling approach has been used by the authors in the past in order to study the injection system behaviour [16][17][18].…”
