Abstract

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.
