The present study is focused on the dynamics of a liquid film produced by spray impact. It is aimed at better understanding of the hydrodynamics and heat transfer associated with spray impact onto a heated target and at providing a basis for the reliable modeling of spray cooling. In this paper the phenomena associated with spray impact, observed under terrestrial and microgravity conditions, are compared. A robust method of film characterization is proposed. We show that a thin liquid film is created by spray impact even under microgravity conditions. However the film thickness increases as the gravity force reduces.
