In order to examine how flexibility affects swirl formation on an intake manifold, this paper presents the computational investigation of a fluid–structure interaction for a flapping flexible plate (FFP) in fluid flow. The system coupling module's commercial code, “ANSYS,” is used to carry out the numerical simulation. The partitioned strategy that underpins this system connection necessitates ANSYS Fluent and ANSYS Mechanical co-simulation. Based on the Reynolds numbers set to 104, three flapping flexible plate (FFP) heights are chosen. Flap oscillations in flexible instances create complex, coherent vortices that separate from the flap tips, increase velocity gradients, and create an unsteady turbulent flow. Numerical results have been presented, including the streamline, velocity whirling strength, Von Mises stress, and displacement distribution. We are especially interested in studying the evolution of the plate's displacement field and the dynamic behavior of flaps.

摘要

In order to examine how flexibility affects swirl formation on an intake manifold, this paper presents the computational investigation of a fluid–structure interaction for a flapping flexible plate (FFP) in fluid flow. The system coupling module's commercial code, “ANSYS,” is used to carry out the numerical simulation. The partitioned strategy that underpins this system connection necessitates ANSYS Fluent and ANSYS Mechanical co-simulation. Based on the Reynolds numbers set to 104, three flapping flexible plate (FFP) heights are chosen. Flap oscillations in flexible instances create complex, coherent vortices that separate from the flap tips, increase velocity gradients, and create an unsteady turbulent flow. Numerical results have been presented, including the streamline, velocity whirling strength, Von Mises stress, and displacement distribution. We are especially interested in studying the evolution of the plate's displacement field and the dynamic behavior of flaps.
