Findings

Derived a theoretical relation for drop terminal velocity.

Validated the relation through experimental measurements.

Confirmed the model with numerical simulations.

Abstract

The problem of the movement of the drops in a continuous environment represents a fundamental step for the study of two phases flows. Their domains of application are enormous as: the combustion of the rooms of the machines thermal, extraction of a liquid of another liquid, catalyst used to trigger the chemical reactions occurring in access points, sparkling absorption by the drops of water in meteorology. The object of our work is to translate the movement of the immiscibles drops in water by a relation expressing the terminal velocity of the drop according to her equivalent diameter. This relation although theoretical has been validated by the experimental and numeric model.
