Strength Analysis of Gas Turbine Compressor Impellers Based on Fluid-thermal-solid Coupling Method
摘要
Abstract
A fluid-thermal-solid coupling platform is established on ANSYS Workbench.To analyse strength of the gas turbine compressor impeller of a transonic speed gas turbine under combined loads,including pressure,temperature and centrifugal force.The conputational scheme contains three modules and data transmission among them.Skills and strategy in the conputational process are presented.The CFX was used to analyze the fully three-dimensional flow field of the compressor.The distribution data of temperature and pressure on the flow-solid interface obtained from the flow field calculation are transmitted to impeller surface.The steady-state temperature field of the impeller is calculated under the Steady State Thermal module,and the results are transferred to structural module.Finally the strength analysis of the impeller was carried out under the combined effects of pressure,thermal and centrifugal load.The feasibility and accuracy of the conputational scheme are validated.Providing the Engineering design and calculation method for this kind of impeller strength analysis and reliable design.关键词
