Abstract:
1. A mist generating apparatus having a longitudinal axis and comprising: first and second opposing surfaces which define a transport fluid nozzle therebetween; and a working fluid passage having an inlet connectable to a supply of working fluid, and an annular outlet on one of the first and second surfaces, the outlet communicating with the transport fluid nozzle; wherein the transport fluid nozzle has a nozzle inlet connectable to a supply of transport fluid, a nozzle outlet, and a throat portion intermediate the nozzle inlet and nozzle outlet, wherein the nozzle throat has a cross sectional area which is less than that of both the nozzle inlet or the nozzle outlet; wherein the nozzle outlet defines a slot on an external surface of the mist generating apparatus; wherein the working fluid outlet is substantially annular and concentric with the longitudinal axis; and wherein the transport fluid nozzle projects radially from the longitudinal axis such that the nozzle defines a rotational angle about the longitudinal axis so that a flow of transport fluid passes through the nozzle throat and accelerates the transport fluid to apply a shearing force to a working fluid in communication with the transport fluid nozzle from the working fluid outlet and atomises the working fluid to form a mist of vapour and working fluid droplets.
