Abstract

The water drop impact conditions prevailing in several rotating arm facilities are analyzed. Indirect measurements of the water drop impacts on polymethylmethacrylate specimens were made when each facility was operating in order to evaluate the effects of the aerodynamic interactions on the actual water drop impact conditions in each facility. These results are contrasted with the static measurements of the water drop dimensions in order to demonstrate the consistency between the static evaluations and the dynamic operating conditions unique to each facility. It is found that the stated monodispersed distribution of 2.0 mm spherical water drops in these facilities is actually deviating significantly from this idealized condition when they collide with the specimen.
