Reed valve simulation using 3D high-order finite volume and finite element methods.

Summary

The shear locking effect occurs in bending-dominant computational solid dynamics problems due to the inability of the element edges to bend, causing the appearance of artificial shear deformation. A common real example where this effect appears is in compressor reed valves. The problem can be solved by using very refined meshes or by employing high-order discretization models. This is straightforward in FEM but not fully mature for FVM models. In this work, a reed valve problem with impact is solved by means of the high-order FVM structural dynamic solver previously presented by the authors. A new strategy to deal with the impact between the valve and the solid seat is presented. Results are verified by comparison to a past experimental work and compared to those obtained by a structural FEM solver, demonstrating the reliability of this new FVM-CSD methodology.
