Abstract
Analysis of sub-processes of spreading and receding of sessile droplets on a hot substrate
Highlights
Since the last decades, many researchers have worked on various hydrodynamic aspects of the liquid film layers
Simulation and prediction of thin-film layer behavior is attracting attention. Many technical applications such as gasoline direct injection (GDI), ink-jet printers, and medical devices are affected by thin liquid film layer formation
According to Schulz et al [11] the fuel film residual formed on the cylinder wall and piston surface during the spray/wall interaction in homogeneously charged GDI engines is in the range of 5μl
Summary
Many researchers have worked on various hydrodynamic aspects of the liquid film layers. Simulation and prediction of thin-film layer behavior is attracting attention. Many technical applications such as gasoline direct injection (GDI), ink-jet printers, and medical devices are affected by thin liquid film layer formation. The spreading and receding behavior of real gasoline completely differs from that of isooctane. In order to predict exhaust emissions, the modeling of thin wall films is being intensively pursued [3] This can only succeed, if corresponding experimental data is available for the validation of the simulation models. There is a wide range of studies that have investigated the behavior of different one or multi-component (b) Isooctane (a) Gasoline
