Two methods are used to parametrize the circulation distribution for compressor blades. Dawe's code is used to predict the viscous effect. An automatic optimization algorithm is developed to minimize the loss with respect to the design parameters.
The aerodynamic optimization of centrifugal compressors requires better understanding of different sources of loss. In this webinar, we will use entropy production rate to distinguish the different sources of loss in a subsonic and a transonic centrifugal compressor impeller under different operating conditions.
