Use of de laval nozzles in spray forming

Powder Stream Characteristics in Cold Spray Nozzles

The exponential increase of industrial demand in the past two decades has led scientists to the development of alternative technologies for the fast manufacturing of engineering components, aside from standard and time consuming techniques such as casting or forging. Cold Spray (CS) is a newly developed manufacturing technique, based upon the deposition of metal powder on a substrate due to hig...

Efficient Simulation and Optimization of Rotationally Symmetric, Converging-Diverging de Laval Nozzles for Twin Wire Arc Spraying

Recent developments in the design of rotationally symmetric, convergingdiverging de Laval nozzles for the use in twin wire arc spraying processes are discussed. Various aspects of an efficient implementation of the proposed gas dynamics solution algorithm on modern multiand many-core architectures are addressed. Finally, a general framework for the application of massively parallel, derivative-...

Characterization of Cryogenic Spray Nozzles with Application to Skin Cooling

* Corresponding author: Beckman Laser Institute and Medical Clinic, University of California Irvine, Irvine, CA 92612. e-mail: [email protected] ABSTRACT Cryogenic sprays are used for cooling of human skin during laser treatments of hypervascular lesions, such as Port Wine Stain birthmarks. In this work, six straight-tube nozzles, including two commercial nozzles, are characterized by obtain...
