Fluid topology optimization and additive manufacturing of a liquid atomizer using an extensive number of grid points

Abstract Additive manufacturing (AM) can fabricate complicated shapes and is useful when topology optimized shapes. Fluid parts often consists of three dimensional curves that are suitable for AM fabrication. However, the application fluid optimization has not been investigated yet. modeling solving an problem have a real industrial with tiny channels, i.e., liquid atomizer which equipped aero-engine fuel injector. In order to reduce computation time, important issue in problem, instantaneous sensitivity approximation method used as method. The part exhibited reduction pressure loss compared conventional part.
