| Abstract:In order to analyze the influence of shrouds structure on temperature袁a HPT shrouds was taken as the research object and
simplified under certain flow and boundary conditions. This paper used 3D numerical simulation method to calculate and analyze the
influence of impingement distance on shrouds surface maximum temperature and temperature distribution in the steady state, and
recommended the optimized impingement distance as 6.5 times as the aperture by considering the temperature level and distribution of the
shrouds. These works could direct and benefit the HPT casing design and improvement. |
