Heat flux and temperature determination in a cylindrical element with the use of Finite Volume Finite Element Method

摘要

This paper presents a method to determine the local heat flux and temperature distribution on a thick cylindrical surface through the solution of an inverse heat conduction problem (IHCP). In particular, the method is developed for cases when traditional measurements cannot be performed due to difficulties in accessing the surface; a common situation in engineering and research practice. In particular, inverse methods are sensitive to measurement errors, for example, those caused by a mispositioned temperature sensor on a solid body. Hence, this paper proposes a method that is insensitive to, and can accurately be used, even in presence of these errors.
