Air-Solid Coupling Simulation Test on a New Designed Porous Structure Intake Distortion Generator Based on ANSYS WOEKBENCH

Aiming to a new designed porous structure intake distortion generator, applying ANSYS WORKBENCH to process air-solid coupling simulation test to validate its strength. The main function of the facility is to form a target distortion flow field at inlet of a fan component test article to satisfy the testing requirement. Consider that this facility is characteristic for its porous, anomalous structure, which may introduce series zones of stress convergence, to avoid instinct plastic deformation or even structure breakdown occurring on the facility in the process of test, before its going into operation, strength validation on the facility under various working conditions is required to ensure its validity and security. Furthermore, in the condition that the strength of the facility does not ample to satisfy the requirement, based on the simulation results structure modification and reinforce schemes are given, further air-solid coupling simulation on modified structure of intake distortion generator strength are performed to evaluate the facility reliability.
