“…where K is an universal constant with a value of 1.26 [24]. Thus, as the momentum flux is similar for the three fuels, a narrower spray cone angle implies a higher tip penetration.…”

“…It also suggested that the effect on the spray mixture formation was stronger with increasing the density and viscosity of biodiesel. Desantes et al [24] established a model predicting the spray axis velocity and spray tip penetration with a series of assumptions. It was based on momentum flux conservation along the axis, and the model was validated by experimental results.…”

“…the jet's "centerline". There are some models [5,3,17,18,13] which apply Gaussian velocity distributions as initial assumptions; however, this calculation will be included in a later work since we anticipate that it would not lead to a major refinement of the axial centreline quantities.…”

“…Notwithstanding, several such models have been attempted to describe different aspects of the jets in this regime. For example, differential equations for a fuel jet's tip penetration distance as a function of time [1,2,3]; models for the gas entrainment rate in a full-cone spray [4]; and a one-dimensional model for the induced air velocity in sprays [5]. None of these models is sufficient by itself as explained below.…”
