| Abstract: | In this paper,the boundary element method is applied to steady-state and
transient heat conduction problems.Some improvements of corresponding
discretization and relevant numerical technique for the boundary integral
equations have been made.For the purpose of testing,several applications are
presented which show some of the advantages of the method in the solution of
thermal problems.Finally,the transient temperature variation of the first
steady-stage aero-gasturbine blade in the sudden drop of the temperature of
inflow gas is calculated and analysed by the method,which further shows the
evidently superior potentials of the boundary element method in the solution of
transient thermal problems. |
