- Abstract
- Experimental studies investigating the break-up of liquid drops impacting on immiscible target liquids have been undertaken. The critical falling height at which the first break-up occurs has been found to be proportional to the drop mass to the power of -0.65+/-0.05, irrespective of change in physical properties of either drop or target liquid, and can be related to the drop mass by the following equation: H-cr =k(c)W(n) where H-cr is the critical falling height, k(c) is the proportionality constant, W is the mass of liquid drop, and n is the power (-0.65+/-0.05). The value of k(c) varies with change in physical properties of drop or target liquid, and hence the critical falling height is dependent on the physical properties of both drop and target liquids. The mechanism of the first break-up changes from the cavity-pulled to the rebounding-jet break-up as the viscosity of either the drop or target liquid increases.
