Three dimensional finite element analysis of radial-flow impeller temperature field

The technique of three dimensional solid element model and assembly was used to determine the temperature field of radial-flow impeller. The FEM software Cosmos was applied to analyze model system, and the precise analytic results were obtained. The results show that the analytic model can reflect the stead-state and transient temperature field characteristics of impeller directly, and thus can be worthy reference to analyze and calculate the temperature field of impeller in engineering design.
