유체-구조 연성해석을 이용한 능동/수동 유동제어방식이 결합된 고하중 축류 팬의 성능특성 연구 = Investigation on Aerodynamic Performance of a Highly-Loaded Axial Fan with Active/Passive Flow Control Using FSI Analysi

다국어 초록 (Multilingual Abstract)

An investigation on aerodynamic performance of a highly-loaded axial fan has been conducted to find the effects of tip injection and casing groove on aerodynamic performance in this study. Three-dimensional Reynolds-averaged Navier-Stokes equations with k-ε turbulence model were used to analyze the fluid flow in the fan with Fluid-Structure Interaction (FSI) analysis. The hexahedral grid was used to construct computational domain, and the grid dependency test drew the optimal grid system. FSI analysis was also carried out to predict the deformation of rotor and stator blades, and the effect of deformation on the aerodynamic performance of axial fan was analyzed compared to the performance predicted without FSI analysis.
