An inverse control volume code is developed for the study of transient boundary inverse heat conduction problems. A nonlinear numerical formulation of the Weber method is extended to relatively high noisy input data. The control volume method is combined with a digital filter method for solving the hyperbolic approximation of the inverse heat conduction problems. The results show that such combination allows to obtain more accurate results. This proposed solution method can be used to estimate the boundary conditions basing on the temperature history at an interior point inside the body. The accuracy of the method is verified by comparison with the analytical (exact) solution of a direct problem.
