Experimental study of drop impacts and spreading on epicarps: Effect of fluid properties

► Drop impact of liquids on solid is a very complex problem. ► Prediction of ξmax is needed in many spray applications. ► Drop impact behavior on banana and purple cabbage epicarps is detailed. ► Viscosity and surface properties of the epicarp have a great influence on dynamic of impact. ► A new model is proposed to describe ξmax as an function of Re and We.
