THERMO-MECHANICAL COUPLING BETWEEN THE FLOW OF STEAM AND DEFORMATION OF THE VALVE DURING START-UP OF THE 200MW TURBINE

Abstract

The lifetime estimation of power station structures and components, subjected to fatigue loading, is essential for determining the moment of repair or replacement. Therefore the degradation behaviour and damage development within material should be very well understood. This research focuses on a fluid-solid interaction that has been developed in Finite Volume Method software for description of heat and flow loading on a cut-off valve and Finite Element Method software for conduct researches on fatigue and creep damage of the valve material.

Keywords:

fluid-solid interactions, compressible flow, heat, creep, damage, fatique, FEM, FVM, stresses
