流体解析と3Dプリンター技術の送風機開発への適用

抄録

We are promoting cooperation of fluid simulation, rapid prototyping and evaluation, focusing on 3D-CAD data, for blowers that are products based on motor technology. Parallelization and multi-case of simulation are realized by using open source software for fluid simulation. By using a 3D printer that uses materials such as powder and photo-curing resin for trial production, shortening of the period is realized. By using a 3D printer that uses materials such as powder and photo-curing resin for rapid prototyping, we realize shortening of the evaluation period. As an example, we show the comparison of the characteristics of a real product and a rapid prototyping by the 3D printer in a small (about 100 mm in diameter) and high-speed (about 15,000 revolutions per minute) centrifugal blower. Also, we show visualization of flow simulation results for the same products.
