Wall boundary conditions in 2.5 D analysis

    • Luigi0


      I want to simulate acoustophoresis phenomena.  My system is composed by a fluid domain surrounded by a mechanical structure and a piezoelectric transducer. The fluid domain has an inlet where the fluid (water) and particles are inserted.

      The fluid part is a parallelepiped, the simulation is a 2.5 D with only one element on the width (z axis), in order to mimic a 2D analysis. My model is a sort of slice of a 3D model.

      What boundary conditions should i apply on the lateral faces? I cannot apply no slip condition, because in reality the fluid domain extend in the z-direction.
