Abstract: A general numerical model is presented to identify multi-variables, including thermal parameters and boundary conditions for inverse heat conduction problems in transient state. Sensitivity formulas are derived. A conjugate gradient technique is employed. The effects of the number of sample points, the data noise and initial guess on solutions are given. A numerical calculation is performed and discussed.
