Abstract: A partitioned time marching algorithm is used for the thermal-fluidstructure interaction analysis based on solutions of the fluid (include thermal) and structure (include thermal) sub-problems. The finite volume method is used for the fluid sub-problem, and the finite element method is used for structure sub-problem. A new data exchange method is presented by Kriging model, which could be used for data exchange on the coupled interface from fluid to structure and structure to fluid. A flow field mesh update method is presented based on the hypothetic elastomer finite element method. A case of multi-field coupling analysis of single-stage bladed disk system in a compressor is investigated. The effect of different loading modes on mechanics characteristics of bladed disk system is discussed. [Received 17 August 2016; Revised 14 November 2016; Accepted 16 November 2016]
