deposition distance d0 play important roles in the contour and the wall thickness of the spray formed tube. But the angular velocity ω of the substrate has little effect on the buildup of the deposit... the deposition rate is corrected, is developed to predict the shape evolution of the tubular product prepared by spray forming. Based on the numerical results, the effects of the main processing parameters......
