How much a geometrical model of a honeycomb seal can be simpli ed in the CFD calculation

Abstract

This paper presents the inuence of geometry simplication on the results obtained in the computational fluid dynamics simulation. The subject of simulation was part of the honeycomb seal located at the inlet to high pressure part of a steam turbine. There were three different geometrical models assumed in the calculations. First one was two-dimensional case and two others were three dimensional, one with the radius of curvature and one without. Numerical simulations were performed for 15 sets of boundary conditions to compare ow characteristics for each geometrical case.
