- Abstract
- In this study, a new concept is proposed in order to simulate the behavior of a multicomponent fuel spray impinging on a hot surface. The distillation curve of the fuel is considered so as to describe the vaporization property of each component in the gas oil, since the superheating degree of the surface, defined by the temperature difference between the wall surface and the fuel saturated temperature, affects the solid-liquid boiling state. First, some impinging sprays consisting of a single-component fuel are calculated to confirm the difference in vaporizing characteristics and impinging behavior in each fuel. Second, a spray impingement submodel is made. In this model, the difference of droplet breakup, reflection, and dispersion process with the difference of boiling state is considered based on several experimental results of impinging droplets on a hot wall. This new submodel is incorporated into KIVA-II code. The results calculated by this model are compared with those obtained by KIVA-II original code.
