建立了一维对流-导热模型,经理论推导、分析验证得到了热障涂层隔热有效性判据:当涂层热阻大于无涂层时高温燃气侧换热热阻时,涂层总能使叶片金属基体外表面温度降低,起到隔热效果;反之,则喷涂热障涂层(TBC...
Endothelial cells (ECs) that reside on the surface of blood vessels are constantly exposed to mechanical stimulation, including shear stress. Fluid shear stress (FSS) controls multiple physiologica...
中国机场通常采用板宽不超过5 m的水泥混凝土道面板,国际上已有机场采用板宽6 m以上的水泥混凝土道面板。相比大尺寸水泥混凝土道面板,小尺寸道面板容易产生病害。为了研究道面板尺寸对道面性能的影响,基于弹性...
Blended-Wing-Body (BWB) aircraft have a relatively short fuselage and no horizontal tail, and they usually adopt podded engines and a V tail instead of a vertical tail. Generally, BWB aircraft have...
The autonomous and controllable Dual Synthetic Jet Actuator (DSJA) is firstly integrated into the Unmanned Aerial Vehicle (UAV), and flight tests without the deflection of rudders are carried out...
