Estimation of thermal conductivity, heat transfer coefficient, and heat flux using a three dimensional inverse analysis

摘要: Abstract This paper presents a numerical inverse analysis to estimate the thermal conductivity, heat transfer coefficient, and flux in three dimensional irregular bodies steady state conduction problems. In this study, 3-D elliptic grid generation technique is used mesh body. The Laplace equation solved computational domain compute temperature at any point meshed A novel very efficient sensitivity scheme introduced coefficients gradient based optimization method. Using scheme, one can solve problem without need solution of adjoint equation. main advantages are its simplicity, accuracy, independency number direct from unknown variables which makes presented here accurate efficient. conjugate method (CGM) minimize objective function difference between computed on part boundary measured temperature. obtained results confirm that proposed algorithm accurate, robust,
