As for a centrifugal compressor design, one factor experiment was the main idea to check the influence of each shape parameter, and a systematic examination wasn't done enough. Therefbre, by letting the quality engineering apply to the simulation used for the centrifugal compressor design, and by optimizing repeatedly, conditions of optimum design were sought. When the air mass flow for input and the pressure ratio for output were chosen, the optimum shape showed a high-pressure ratio. In this case, high-pressure ratio led to high efficiency. But as an assignment from now, it showed that some measures would be needed to deal with the case of when any convergence answers were not given. Also through this parameter design the points to be paid attention to when quality engineering is applied to the simulation are mentioned.
