Abstract:

Is developed the methodology for determining two-dimensional temperature fields in multi layer sections of a complex profile using the finite element method based on rectangular finite elements that due application of minimum number of elements in the assembly gives the possibility to construct a flexible scheme for solution of steady and non-steady equations of heat conductivity. The task of propagation of unsteady temperature fields and analysis of stresses caused by pressure and temperature field from the attached technological unit to the cooling flange using a conical adapter has been solved, and programs have been developed for analysis of this unit taking into account steady and non-steady technological modes
