Abstract Gas-atomized spray deposition(SD) process is used for the manufacture of rapidly solidified bulk and near-net-shape preforms. The mass, momentum and energy transfers of the gas and the atomized droplets during atomization have great influence on the microstructures and properties of the deposit. The flow behaviour of the gas and the droplets are studied based on the mass, momentum and energy conservation theory. The mathematical model of the three-dimensional flow of the gas and droplets is proposed, and the controlling equations of the flow are deduced.

Key words: gas atomization rapid solidification fluid flow
