Abstract:Inversion of effective conductivities for honeycomb sandwich is of great importance for optimal design of TPS. Boundary element expressions of anisotropic heat conduction equations are derived by Gauss theorem, radial basis function and radial integration method. Coupled with Newton-Raphson and complex variable methods, effective conductivities for honeycomb sandwich are inversed. Shape functions, Gauss quadrature and radial basis function interpolation are applied. The methods are validated by honeycomb sandwich structure consisted of four honeycombs. The work simplifies the multi-region into one region, and provides advantages for heat transfer calculation in honeycomb sandwich structure consisted of many honeycombs.
