Abstract

In gas turbines, melted particles are cooled and adhere on surfaces of turbine blades and endwalls. The deposition phenomenon results in decrease of turbine performance while its mechanisms are still unclear. In this study, the deposition phenomenon is investigated by means of three-dimensional numerical simulation with an adherence model by considering the latent heat. We have compared the obtained diameter of the adhesive droplet with the experimental data and confirmed that the present method can predict the droplet behavior well. Fingering shapes of the droplet are observed, which are also found in the experiments with the same condition.
