ABSTRACT
A method for deflecting high velocity liquid nanojets through nonuniform asymmetric heating of a cylindrical nozzle is described using molecular dynamics simulations of liquid propane. The deflection originates mainly from a strong, highly nonisotropic evaporation flux from the liquid near the exit, resulting in overall cooling and a force that bends the nanojet in the lower temperature direction. Also discussed is the formation of a self-convergent virtual nozzle in the injector-confined liquid with an exit radius smaller than that of the injector, portraying the temperature and density profiles in the heated liquid and resulting in a nanojet of reduced dimensions.

    A new method is reported for deflecting a microscopic jet emanating from a nozzle away from the nozzle's axis of symmetry. It relies on putting energy into the jet through an asymmetric heater embedded in the nozzle. This novel phenomenon is probed theoretically. It is shown that jet deflection...
