A sensitivity analysis for general evaluation of the influence of thermal boundary conditions on the natural convection heat transfer is proposed. In order to seek the sensitivity function, we employ the perturbation formulas for the governing equations of the natural convection field and derive their adjoint operators. Then, the sensitivity function is obtained using the numerical solutions of the unperturbed heat transfer problem and the perturbed adjoint problem. As a result, the change of total heat transfer from an original one can be calculated by an inner product of the sensitivity function and the perturbation of the thermal boundary conditions. The sensitivity functions for the natural convection heat transfer in a square cavity are presented to demonstrate the proposed method.
