J. Taler et al., MONITORING OF TRANSIENT TEMPERATURE AND THERMAL-STRESSES IN PRESSURE COMPONENTS OF STEAM BOILERS, International journal of pressure vessels and piping, 72(3), 1997, pp. 231-241
Two methods of solving the transient inverse heat conduction problens
in complex shaped elements are presented in this paper. The time-space
temperature distribution in whole element cross-section is reconstruc
ted using the measured temperature histories at several points placed
inside the element or on its easily accessible outer surface. Thermal
stresses are then evaluated involving Finite Element Analysis. In both
methods the heat transfer coefficient at the element inner surface is
the unknown value. Four examples are presented, two for one method sh
owing the high accuracy of the presented methods and possibility of th
eir practical application. (C) 1997 Elsevier Science Ltd.
