In this paper we investigate phenomena associated with particle impingement on dynamic airfoils. Using an Eulerian based solver, a droplet velocity field is computed throughout the computational domain. This solver is used to scrutinize particular concepts, with the intent to save computation time, listed as follows: (i) The applicability of different time-averaging techniques to calculate an average local collection efficiency for dynamic simulations. (ii) Comparison between static and dynamic bodies undergoing particle surface interactions. (iii) The use of a numerically viscous solution to the Euler equations instead of a fully viscous solution to predict proper particle trajectories on dynamic airfoils. Guidance is provided herein, for the applicability of solution methods to reduce computational costs.
