A space marching method for multidimensional transient inverse heat conduction problems

A new method for the solution of multidimensional heat conduction problems is formulated. The developed space marching method allows to determine quic kly and exactly unsteady temperature distributions in the construction elem ents of irregular geometry. The method is especially appropriate for determ ining transient temperature distribution in thick-wall pressure components based on temperature measurements at the outer surface. Two examples are in cluded to demonstrate the capabilities of the new approach.
