| Abstract |
A coupled analysis of rod growth model using vector calculus and heat transfer model using boundary fitted coordinate has been formulated. Temperature profile in a spray formed rod of 2024 aluminum has been calculated by the proposed model. At initial stage of spray forming. the temperature of substrate and preform increases rapidly. And then temperature of the vertex point is kept as about 525℃ During the cooling stage after the spray farming steps, temperature of all points inside rod decrease and the cooling rate of surface is higher than that inside the rod. |
