Multi block and parallel computations of rotor fan using three dimensional euler equations

Abstract

The aim of this study is to develop an efficient fan/compressor rotor analysis tool using Newton-GMRES method. Three dimensional Euler equations are solved for transonic compressor rotor. Solution method is a matrix free solution technique hence it is not required the Jacobian matrix evaluation and flow equations are solved implicitly. Governing equations are casted into rotational coordinate system to make the problem available to use implicit solver. Computational domain is divided into optimum number of blocks and each block is solved by different processor using parallel computing. NASA Rotor 67 transonic fan is analyzed by solver and solutions are compared with the experimental test results of NASA. © 2018, American Institute of Aeronautics and Astronautics Inc, AIAA.
