Topology optimization of flexible micro-fluidic devices

摘要: A multi-objective topology optimization formulation for the design of dynamically tunable fluidic devices is presented. The flow manipulated via external and internal mechanical actuation, leading to elastic deformations channels. objectives characterize performance in undeformed deformed configurations. layout fluid channels determined by material optimization. In addition, thickness distribution, distribution active support conditions are optimized. coupled fluid-structure response predicted a non-linear finite element model hydrodynamic lattice Boltzmann method. Focusing on applications with low velocities pressures, structural due fluid-forces neglected. mapping scheme presented that couples distributions mesh. governing adjoint equations resulting interaction problem derived. proposed method illustrated manifolds.
