Analysis on Heat Transfer Characteristics of Film-based Structures with Temperature Sensitive Paint in Hypersonic Wind Tunnels
摘要
Abstract
The phosphor thermography technology is one of the key technologies to measure the thermal environment of aircraft model surface in the flow fields of hypersonic wind tunnels.However,there is still a lack of systematic research on the heat transfer characteristics of film-based structures with temperature sensitive paint(TSP)and the applicability of film-based materials.Therefore,a numerical simulation analysis on the internal heat transfer characteristics of TSP film-based structures with different material thicknesses under different flow field conditions is carried out.The effects of therunning time,surface heatflux,and TSP layer thickness on the internal thermal diffusion depth and surface temperature rise of the film-based structures with different material systems are studied for hypersonicshock and blow-down wind tunnels.The results show that the internal thermal diffusion depth of the TSP film-based structure is mainly related to the thermal diffusion coefficient of the model material and the running time,and is less affected by the heatflux and the TSP layer thickness.The surface temperature rise mainly varies with the heatfluxand TSP layer thickness,and the changes both are positively correlated.The research results could provide theoretical support for the customized design of the material and thickness of film-based structures in the applications of phosphor thermography in wind tunnel tests.关键词
