Passive diode-like device for fluids

Case ID:

C12880

The present invention is directed to an improved fluid diode using topology optimization with Finite Element Method (FEM). Topology optimization as a flexible optimization method has been extended to the fluid field. For given boundary conditions and constraints, it distributes a specific amount of pores (or remove materials to get channel) in the design domain to minimize/maximize an objective function. In this design, inlet and outlet ports are aligned and inflow and outflow are in the same direction. The present invention features an intricate network of fluid channels having optimized fluid connectivity and shapes, which significantly improves the diodicity of fluidic passive valves.
