概要
Abstract This paper presents steady-state Eulerian thermal analysis of welds using moving coordinates that has been reported as computationally very efficien t method. This method requires much less CPU time than conventional Lagrangian method in which heat source moves in computational domain. This kind of Euleri an analysis can be done conveniently by using computational fluid dynamics code. To show the availability of this method, it is applied to a groove weld of a core shroud in a boiling water reactor, with Goldak heat source model applied. Temperature histories from numerical results agree well with measured results.
