TY - JOUR TI - Hybrid textile composite fan with smart and fractal structure AU - Chen Xiao Dong AU - Qiu Li AU - Nan Yanmin AU - Chen Ze Lin AU - Li Jing JN - Thermal Science PY - 2021 VL - 25 IS - 2 SP - 1329 EP - 1335 PT - Article AB - It is a key issue to embed sensing components in a smart material. A fractal-like distribution of sensing components is considered in this paper to collect data for smart-type fan test blades with hybrid textile composite, which is proved to have self-monitoring property. A fluid-solid coupling model is proposed to analyze the functional relationship among the hybrid fiber arrangement and morphology and the mechanical properties of blade in each force point. It is concluded that the deformation and the self-adaptability of flexible fan blades are two main factors affecting power efficiency.
