Abstract

Abstract:

Steady and unsteady simulations are conducted on the investigation of the deterministic unsteady phenomenon in the first stage of NASA 67. Firstly results from steady and unsteady simulations are compared and typical rotor/stator interactions are analyzed. Then the distributions of deterministic stresses in the blade passage and the components of deterministic stresses based on velocity decomposition at the rotor/stator interface are studied. The discussions can reveal some shortcomings of the present deterministic stresses models and make some contributions to the modeling development.
