<p>The invention is directed to a stable capillary microjet and a monodisperse aerosol formed when the microjet dissociates. A variety of devices and methods are disclosed which allow for the formation of a stream of a first fluid (e.g. a liquid) characterized by forming a stable capillary microjet over a portion of the stream wherein the microjet portion of the stream is formed by a second fluid (e.g. a gas). The second fluid is preferably in a different state from the first fluid-liquid-gas or gas-liquid combinations. However, the first and second fluids may be two different fluids in miscible in each other. The stable capillary microjet comprises a diameter dj at a given point A in the stream characterized by the formula:wherein dj is the diameter of the stable microjet, +E,otl =+EE indicates approximately equally to where an acceptable margin of error is +/-10%, rho 1 is the density of the liquid and DELTA Pg is change in gas pressure of gas surrounding the stream at the point A.</p> |
