The present paper describes research to determine the lift and drag forces on a single heptane droplet in a non-uniform flow field over a range of Reynolds numbers of 1-30. Experiments are described for droplels (90-320μm) entering a jet of air (≈ 1 m/s) and fallowing unsteady curvilinear trajectories (for which few experimental studies and no theory exist). The lift and drag forces acting on the droplet are compared to those predicted by the most closely related theory and engineering formulae. The results support standard correlations and suggest that additional effects such as Basset forces reach not more than ten percent in these experiments.
