Abstract:Based on the studies on spray forming process, a computer model has been developed to describe the dynamic and thermal behavior of droplets in the stage of flight during the spray forming process. In this computer model, the velocity of atomization of droplets, the thermal profile of the droplets in flight, solid fraction of the droplets and the spray were studied . According to the model, the dynamic behavior and thermal behavior of aluminum are calculated and discussed.
Key words: spray forming process; computer simulation; droplet
