Abstract

The objective is to determine the surface properties of liquids which influence spray formation, and to show how surface rheology can be incorporated into models of spray formation to predict spray quality for liquids containing surface active agents. The approach will be to investigate the short timescale behaviour of antifoaming agents and to develop an experimental methods for relating this to spray formation. We will also investigate the surface rheological properties of surfactant solutions. The research is important for under- standing how to maximise the efficacy of spray application; the effects of liquid properties on spray droplet size distribution are not fully understood, and work on pure liquids and on surfactant solutions has shown that changes in spray formation cannot be fully explained by changes in surface tension or bulk liquid properties. Moreover recent work has shown that the effects of liquid properties are also dependent on spray nozzle design. It is hoped to develop collaboration with industry and with a university food science department.
