热辐射对双陶瓷层热障涂层的隔热影响
Effect of heat radiation on the thermal insulation of double-ceramic-layer thermal barrier coatings
摘要
Abstract
Opaque and translucent physical models of double-ceramic-layer thermal barrier coatings（DCL-TBCs） were established with the theory of heat conduction,convection and radiation.The steady temperature field was simulated with ANSYS software.When the ceramic is opaque,with the top ceramic layer thickness increasing,the upper side temperature of the top ceramic layer linearly increases,but that of the second ceramic and bonding layers linearly decrease.When the double ceramic is weakly translucent,the trend of temperature is similar to the opaque＇s.When the ceramic is highly translucent,with the top ceramic layer thickness increasing,the upper side temperature of the top ceramic layer is a little lower and that of the second ceramic layer is higher than the opaque＇s;the upper side temperature of the bonding layer firstly fast,secondly slowly decreases and then keeps constant,but much higher than the opaque＇s.关键词
