An important characteristic of particle laden, supersonic gas jets              issuing from convergent nozzles is that the particles can be strongly           focused at axial distances which depend on particle (aerodynamic)               size.  This research will investigate experimentally the potential of           this phenomenon for detecting and sizing particles of 1 to 100 nm               diameter.  Particle concentration profiles in the jets will be                  measured using small diameter probes.  The research will include a              theoretical study of gas and particle motion in supersonic jets for             the technologically important jet Reynolds number range 5 to 500.  If           time permits, the generation of ultrafine monodisperse particles by             electrospraying low conductivity, dilute solutions will be examined             experimentally.                                                                                                                                                 The particle focusing characteristics of supersonic jets make them an           attractive tool for rapid detection and sizing of submicron particles.          Such jets may also be attractive for "writing" with small particles on          substrates.
